The single greatest threat to your scenario, though, lies outwith your control: the supply and development of film.
Black/white film poses few processing problems - you can (and should) do it yourself, but colour is something else. Before I became an independent shooter I worked in an industrial photo unit for some years and ended up doing the colour lab stuff; it made me realise that there is a great deal that you can do with colour if you are not working within commercial limits!
And that's where it all goes wrong in a non-service kind of environment: labs simply can't afford the luxury of that one, further test... the customer (the photographer) would not pay the real price of the added hours, and so the concept of 'commercially acceptable' was born. And for anyone without a huge through-put of work, pro or amateur, it just doesn't make financial sense to run colour chemistry. Worse, colour sense is something you have to exercise a lot in order not to lose the fine edge; you can get to a mental position where you begin to doubt your own eyes and opinions of what you are seeing - is it magenta or red, cyan or a shade of blue or green? Even when you do it every day you can lose it when you get tired.
But, for b/w, as long as enough people keep on buying the materials there should be hope, even if prices have rocketed.
