No one in this area would ever pay big bucks for my services
The truth is, no one's likely to pay more than you think you're worth. Somehow, your own self valuation finds its way to the surface.
I don't think anyone (in the wedding video business) is in a more remote location than I am (an hour from the nearest Walmart), nor in a poorer area. And it does affect rates, that's true. But I book $1000 weddings all the time. Booked one for July just today. The same package would go for three grand in Dallas, but then I don't have those big marketing expenses either.
If your work is truly good, then maybe you need to work on marketing (and possibly confidence). Have you ever thought that you might be losing business because some people may think (because of your low prices) that you can't be good, so they don't even waste time asking for a demo video?
Have you done a marketing study? Do you know who your competition is? Do you need to expand your coverage area? I know gas is high, but if instead of four hundred dollars for a local wedding, wouldn't it be worth an hour's drive to get to a $1000 wedding? We drive two to four hours to do weddings, all the time.
