On the side if we did this I thought I'd go work at REI or the local climbing gym or something. Just some place that I don't absolutely hate being where I can make a guaranteed 10-20 hours of terrible wages to pad out the dry spells where we don't have freelance work.
I think if this could be properly balanced I could only work the equivalent of a few full time days out of the week, but also I've never done it so maybe it will just be impossible and consume all my time for no pay.
