is this behind the famous "onions desktops"?
i get a lot of enquiries through word of mouth. I started doing websites for companies that couldn't afford to pay much - charities, new business, personal projects etc. That way you do a standard job, they pay you very little and are very impressed, and tell all their friends.
Another thing i've always thought of doing but never done is a mailshot.
Combine the two, maybe - get down to your local college, they will probably have a photography course, post some stuff on the wall about your gallery - amateur photographers who maybe can't afford much, but are very enthusiastic about getting their site noticed!
hope this helps
