If you could demonstrate that you can really do it, and then amass a supply of film and maybe sell it as a package, with some sort of guarantee or batch testing, because there could always be issues with the storage of the film, given that you would have to acquire film from various unknown sources, then yeah, I'd be willing to pay around US $35-45/roll including processing for that service.

6x17 Kodachrome--yeah, that's worth $10 an exposure.
