This went in an unexpected direction, but yes, I imagine there's plenty of demand for assistants to creative people. And I don't think there's anything wrong with assisting someone. Trouble is, creative people are not always known for having lots of money to spare, though like anything else there will be exceptions. If you widen your search, as Birol said, there are lots of non-writers who could also use a hand, whether it's pulling weeds or clearing out clutter. When we're short on cash we can usually find someone who's relieved to have a few hours of help. I used to think ideas were like gold. But I'm also completely flooded with them: more things than I could ever write (or draw) in a lifetime. The trick is finding time and quiet to do things, without going broke myself.
