Upload & Sell: Off
I've found quite a bit of success with Point of Purchase sales. I'll pick out the best image for a big wall print, send it to Circle Graphics to do a big canvas, and just take it to the sales session.
I'll tell them it was an image I loved and made for my own display--I just brought it to show it to them. Most of the time, they will want to buy it outright once they see it--remember that most people cannot visualize the impact of the images when printed large. Until they actually see it, they can't really image what it will look like. If they don't, I still have it for my own display purposes because it's the image I chose.
After I've used it for a year, I'll offer it again to the client at a lower "used" price. Circle Graphics is inexpensive enough that worthwhile profit will still be there.
