I'd say working for free with few a photgraphers and/or other videographers is
the way to go in the beginning. Offer photogs a free video photomontage of their
work. Have them post it on their site and have your link right there...booyah!

Make a list of all the vendors and venues in your local area, drop by (better
than just cold calling), give'em a demo and get a name. Wait a week, and then
call.."Hi, may I please speak with Jane Doe". And then follow up from there.

It's a start.

With any initial marketing campaign, it's best to do a number of things. Come to
think of it, its best to do a number of things all the time.

Website with demos. Cards with URL.

Hope this help!
