I was thinking about making some more money while staying busy, and wondered about the process. There are plenty of feeble, retired, and/or people who might need help with small projects around here.
Landscaping, painting, minor construction/electrical/plumbing, etc., etc. I've done it all.

Just wondering about the cavaets: What are the lines that can't be crossed? Does one need a General Contractor's or Electrician's license to change a light or fan fixture? A taxi license to take a customer to the store for materials? A roofing licence to caulk edges?
Is bonding and insurance a necessity?
