Find a freelancer to partner with (Score 1)

Go to user groups and look around online, maybe even talk to some of the contractors your employer uses. Many contractors have more work than they can do. I employ several part time subcontractors. They mostly do bug fixes, but the code is interesting and very different from their day jobs. I do a straight pass through to them (I don't take a percentage), but many people do take a cut of work they pass on. This means not having to find the clients your self, keeping the billing simple and helps you keep the small number of hours you want.
