I think the biggest determining factor for pricing is in how comfortable you can make people feel. The more times they see your name and the more common place it becomes the higher the price you are going to be able to charge and the less work it will be to book them. As soon as you give a client reason to doubt you there is a good chance that she will go else where… the doubt can come in the form of prices that don’t make sense (a range of $750-$7,500), a website that doesn’t fit the idea of ‘their wedding,’ a conversation that doesn’t make them feel comfortable or anything else. By contrast, however, you can increase the amount that you can earn quite significantly by exceeding your clients expectations at every step along the way, read the two red sales books by Jeffrey Gitomer

An option to consider, since you haven’t done a lot of weddings yet, is to put up an amazing landing page with your one best image at whatever URL you are eventually going to develop. When people reach out to you, spin the focus to them, you, the connection between the two of you and why you two are the perfect fit. Make a very strong impression on everyone that you speak with so that they have no choice but to book you right then and there because they feel so comfortable with you.
I started doing weddings for <$1000 then increased from there every few months. Whenever I was getting too many calls, booking too many weddings or was getting the wrong type of clients I raised them.
Robin and Dan are both right, figure out what it costs to do a wedding while remaining profitable, it is probably more than what a lot of people in your area are charging. I also think there is value is charging what you want to make because it forces you to become better faster and you are never allowed to become complacent. From my experience in doing business and watching other people make business choices, clients seem to remember numbers more clearly than words, so if you start out at $800, then go to $1200, then go to $1800 then go to $2200 then go to $3000 and so on, it is going to seem like a lot of price jumps, however, if you start at, say, $2000 and add on a little extra product/service (value) to entice people to book you can slowly cut back on the product/service (value) as you become established to make the profit that you desire and need, once that happens you can introduce a more valuable package without losing your old referral base. Eventually you can raise your prices again and do the same thing

-for a starting price figure out what you need to make to stay in business then charge that
-add in a little extra product/service (value) to get people interested and slowly scale that back
-put up a killer landing page with very strong visual impact
-blow people away in meetings and on phone calls
-have a plan that says what you’ll charge, who will pay it, where they’ll find you, the circumstances in which you will discount, the circumstances in which you will raise your prices and what you will do when things are slow
Most businesses start out slow so don’t be discouraged if 2007 is not quite what you hope for, stick with it though and keep pushing forward and it will pay off

PS. depending on your risk tolerance levels there is a lot of value in being first and most... as in the first to start at a higher price than the rest and being the first to charge more than the rest. It is just as easy to fail at $1,000 as it is at $10,000. I can't say if that is right for you or not but it is something to consider
