When you say "side project" how large are we talking? If it has $15~$25k a year of profits or so, consider talking to FEInternational -- I sold both of my companies through them. At the "few hundred bucks a month" level you're probably looking at either Flippa or finding someone through personal networks. You might consider posting on e.g. the Indiehackers forum or HN if you're looking for entrepreneurially interested people with technical skill, FWIW. There have been far less obvious places where business deals started.
