Okay, this has turned into an awesome thread! I've gotten so many good ideas. I wanted to thank and address everybody who has responded so far, so please bear with me... I know I'm long-winded.
Regina - great idea with the chocolates! I'll give that a try. I know chocolate would lure ME in! Thanks for the tips on the slideshow viewing, too. I'll invest in another enlargement and some smaller prints and frames. I just ordered two new sample albums from PictoBooks and they should be here soon.
Swan - in theory, I agree with you and I don't plan on doing bridal shows my entire life. However, 2006 was my first year shooting weddings and for a lot of that time I was a second shooter and not really in a position to get a good WOM train going.

The weddings I did on my own the couples and their families really seemed to genuinely be pleased with, but a small handfull of weddings isn't going to get the ball rolling like I need for 2007, either. So, after much deliberating, I decided that it would probably be a good idea to do this show just to get my name out to more brides. The truth is that right now I am not any better than the other photographers who will be at the show, and even though I'm a big fan of the "start as you mean to go on" mindset and I WANT to be marketing myself to the types who will pay $10,000 for their wedding photography, I need more experience under my belt and more "wowed" clients to get to that point. It's so difficult starting out! *sigh*
Besides, all the referrals I've had so far have been from other vendors, so I'm really looking at the show as a great opportunity to meet more local vendors and start networking with them. They're all in one place, and it'll be so convenient that way, ha ha. My hope is that I can make my booth a little sanctuary of non-craziness and fun and friendliness, so the brides will all want to book me just because it's not a zoo at Libbie's place. Also: Chocolate.

I also agree with you that it's really smoking hot referrals that get you jobs, not quantity - and that all that's required is the emotional impact of a slideshow at the reception to imprint you in people's memories. I'd really love to learn more about how to successfully run a slideshow. I'll have to dig up old threads and figure it out. It's something I definitely plan on doing at all my weddings from now on. The uncle of the bride at one of my summer weddings took photos of the day's proceedings with a little point-and-shoot digital and put a slideshow up at her reception as a surprise - WOW. Even I was moved, and the little gears started turning in my head and dollar signs started shooting out of my eyes. I've been trying to figure out what I need to do it since then!!
Gavin - great idea on the postcards! I ordered some cute appointment cards from OvernightPrints yesterday and I thought about the postcard idea. I might have to do that today.

Good luck in Spokane tomorrow! Sheesh - you're doing a ton of shows - I hope it pays off well for you. Since you're doing Spokane, maybe you're doing Lynnwood/Everett on the 27th/28th? If so, let's meet up and say hi!
Colleen - I like the "information about me and the work I do" idea. I might take that approach. I am getting together tomorrow with several girls to talk about what they would be looking for at a wedding expo so I can tailor my info to fit what my "focus group" says. I have a feeling they'll be more interested in the photos and the person than in the prices - at least early on in their wedding planning. I don't have a logo, but I have an unusual name, so I'm kind of banking on its memorability - like with Bambi Cantrell and Bootsy Holler, right?

And it will be plastered on everything, too! There's so much to get done. And so many marketing books to read.
jkantor - Where are you located? I'm such a newbie here, I don't know. I couldn't find that info on your web site, either. Also, did you know that the Bridal Salons and Photo/Video links on your site are reversed? Oops! Anyway - I'm hoping that the Seattle market is a split between viewing photographers as commodities and viewing them as priceless necessities. How they're viewed here seems to vary depending on which photographer I ask. I really have no idea right now.
stina.tei - Thanks. I am hoping that my nice drawings will really bring folks in. I know how huge a hobby knitting is - it seems like I'm the only woman under 40 who doesn't knit! My sister is an in-demand dyer and her yarn colorways are hard to get, so hopefully that will get the brides talking about my booth.

Plus, the dinner for two at a fancy restaurant - who wouldn't love that? (I'm doing portraits of the head chef's new baby in exchange for that...it's pricey!) I am relying mostly on my personality, so I'll be less windy than I am here (ha ha) and take your advice to only really chat up people who seem very interested. Save my breath!

Lynn - wow, great idea about making the handouts stick out. I really need to give this some serious thought. I'll see what I can come up with. I've heard that the shows are overwhelming, but the one I'm doing isn't quite as huge as some others in this market. Hopefully that will give me some advantage!
Geneve - thank you for the wonderful advice! I'm afraid I don't know what targeted shows are - but I'll figure it out and look into doing some. I like the idea of only giving out the price sheet to folks who seem really interested in me - then it seems like they're getting the favorable inside info to them, I'm sure.

I'm definitely not expecting to make any bookings at a show - I'm not even going to push bookings, but I am going to mention appointments to everybody who seems interested. And I do have a florist friend who would probably be thrilled to get some arrangements into the show. I'll talk to her today! I have been going through Bambi's book, too - and while I sadly don't have the budget this time around to make a knockout booth like hers, I am trying to incorporate her other tips and tricks as much as possible!
Well, thank you everybody SO MUCH for all the excellent advice. I feel so much better prepared now. OSP rocks!
