I wonder if a valid business model in this case would be to get someone involved via profit sharing. I wouldn't find $Xk/month worth while to devote the time needed to improve the product (otherwise I'd be doing freelance), but if I was offered 50% of the profit above what the current profit levels are, then that might be a fun project to take on on the side that would incentivize me to make the product as profitable as possible.
