My town, in a surprisingly conservative part of Louisiana, has an artist residency. They pay $700/month and supply a studio to 3 artists for 9 months out of the year.

The hours are whenever the artist has the time (so as not to interfere with their jobs), and the stipulation is that they have to be available twice a month to teach evening classes about their individual style. They have to have enough pieces by the end to fill a show, as determined by the board that assigned them for the year. But there's no hard number of art pieces required.

All this to say that it can be done. Even if right now it's just a few artists a year in one town, the concept is there.
