I am a photographer with a couple of years new work. I've sold maybe 5 photographs without 'trying.' I have a friend who has offered his beautiful townhouse (complete with garden) to use as a 'gallery' for a photo show. The location is perfect. Now I need people to show up. How can I get a pre-printed (or downloaded) mailing list that I could use to send out postcard/invitations (maybe 500-1,000) to people who are either art lovers, museum & gallery goers, art buyers, photography buyers, other photographers & artists who live in a radius of about 10 miles from the location? (Washington, DC area) so I'm sure there are at least that many. Also, I was thinking that when people walk in, I could give them a door prize ticket and the winner would get a photograph (their choice of photo and framing). Would that seem tacky or not? I figure I'd get maybe 1 in 10 or 20 people who got the invitation to show up. Does that seem about right?
