Hi Mike!
We have done that. Once you do a couple, you'll figure out who to talk to and what kind of stuff to present to them.
We offered this to the location where the image was shot in a nice matted frame for them. They gushed. It quickly circulated b/t volunteers, employees, and curators.
The main thing that we have found - the difference b/t businesses gushing, and a business not wanting to be bothered with it, has to do with whether or not
THEIR name is prominent on it.
Still put your name on it, but their name with central placement, also gets you very nice word of mouth advertising. So far our word of mouth referrals to bookings is 100% and typically include the exactly type of client we love working with. Its a win win situation.
This was a bridal, but we have done that for the vendors we work with at weddings. We do the same thing, but their item is prominent (eg bouquet). The vendors typically get an Art Leather folio to show off their work. That works well too.
Good luck!
