Gavin,
Nice work on the Wordpress customization... that takes some know-how, and it seems to be working well. May I provide a few small stylistic critiques? Clearly these are all matters of taste and others might completely disagree, but for what it's worth:
1. I like the subtle patterned background. Nice colors.
2. I'm not a fan of the Comic Sans font... it just looks rather scrapbook-y and homemade. The photo you've chosen for your main page is elegant and dramatic... the fonts you use for your menu and text remind me of elementary school workbooks. There are plenty of simple, modern, timeless fonts out there that would work better, I believe.
3. Again, love the image on your header, but the edges kind of make it look like one of those clocks from the 1970's with a nature scene painted onto a piece of wood and varnished over. I think a clean border would do it more justice.
4. Drop down menus - the text is centered on the first three, but on the "latest bloggin" menu it's left-justified. I think uniformity would be better.
5. I admit I've never been a fan of Show-It Web as a means to show a portfolio rather than slideshows, but you've pulled it off about as well as I've seen. Nice work.
6. I'm seeing some broken links under the "See Your Photos" page.
7. I definitely like the way your blog integrates right with your site.
8. I know you said you still need to proof the site and make some final tweaks, so you may have been planning on doing some of these things already. I didn't read all the text on your pages, but on the "Meet Gavin" page I noticed the following: "Hi, I’m Gavin, a photographer from Central Washington State. I started my own photography business at age 17, and have grown to where I am now at age 22 I started doing photography as a real interest at about age twelve." My inner grammar police detects a run-on sentence.

I'm such a nerd.
I know Philadelphia is a different market from Washington so perhaps you have exactly the look and feel necessary to attract the brides in your market... just thought I'd pass on some random thoughts that might help. I appreciate the time you take to provide resources to photographers, and hope this does some of the same for you.
