I think you misunderstood me. If they actually want me to show my photos I'll do that for free, no questions asked. I would actually be really happy and amazed to do it. Prints on demand I meant for visitors. Just hang a list of the pictures shown where people can write down their contacts and what they would like, canvas/paper type etc. Then call them and ask if they actually want it, give them a price estimate, then print and deliver.
