You can only charge what your market can bear. My typical booking in Dallas is up around $3200, however if I were in Iowa, it would be a completely different story. People in the UK are amazed at what we make over here in the US.
Having said that, you must define both who you are marketing to, and your skill level of those already in your local business. Study every website and pricing structure of photographers in your area, be realistic about your skills, and then price accordingly. Even if your prices are marginal to high, being of good value is key. Don't be afraid to charge what is reasonable, but also be careful not to price yourself out of the market. Give just one more percieved value than the next guy, and you will book constantly. People don't just want talent, they also want what they perceive is of value.
Know who your target client is. My clients are artistic types with professional jobs, in their mid twenties. Being not so artistically inclined, and self employed in my mid fourties, I had to go to people like my target client and fine tune my presentation. If I were selling to traditional folks in thier thirties, I'd be doing something else entirely, marketing-wise.
So to sum up, know your area market, your target client, and your skill level.........then market using those fields.
