Thank you everyone for your advice. Just for the sake of keeping my options open, how would the IKEA idea work with respect to the film? I understand having the film not attached to the spool and paper so it doesn't react to the paper if its stored for months, but what could the film be kept in that it wouldn't react to?
You can just store it in light tight plastic bags. You can find some on freestyle, that’s how I ship most of my film. I would recommend putting it in two black bags in a rigid container (cardboard box works).

That seems to be the best option. If you were willing to cut to length and then sell 5 spools-worth of film packaged that way, you'd probably do good business and be providing a service people would appreciate. Once you start providing a "finished" product, you open yourself more to the complaints that accompany such things. And @blee1996 is totally correct. The main customers for that film will be people who don't mind winding their own spools (especially if they think it'll save them some money).
Perhaps, but I wouldn't be interested. Finished product of this type is fine with me even with caveats to use quickly and no guarantee. And I'm well-versed in rolling and re-rolling film.
