@Ian Stewart - That's a good point!

Jeff, if you've got good organizational skills, you can basically be a project manager, and outsource the technical bits. Charge clients $50-75/hour (or whatever your market will bear), pay out about 60-70% of that to your outsourced help for their time, and any overhead time (paperwork, conference calls, etc.) you keep all to yourself.

The hardest part is reeling the clients in, and making decent time estimates. Learning to recognize problematic clients and tell them "no" is also essential. :)
