Heh, Eddie, that's getting pretty pricey, indeed.
If it's that bad in the US, it definitely sounds like I could pretty soundly beat that per-roll cost in the right sort of quantities: someone gets five or ten rolls behind, or a few hundred, I could probably work out a mutually-beneficial scheme where I could clear it up with a couple of big tanks.
I run at a different speed than pro labs, but there could be a niche there for hobbyist backlogs.
(Maybe charge by the tank, or something. Big tank vs small tank isn't that big a difference, timewise, and it's not the same kind of overhead as a machine would take.) So, maybe I can hit a niche, there.
My 'RML Enterprises' scheme will be involving a little of this, a little of that, maybe see if anything becomes really profitable that I can actually keep up with, but at least, but the general idea is to be able to do a lot of odd things, since amid the various health issues, I often can't do any one thing all the time, but I can usually do *something.*
