Auto mechanics generally don't make more that $25 an hour-maybe at dealers they make more but I would check that out. Opening your own shop is very expensive. Mobile mechnic's are valuable. Also did some work on mobile auto inspection for people buying cars..I like that can start at couple a grand to 60K....

I think there is a big market for on-site hair cutting (MEN)People are busy and don't have time. Busy executives even retail shop owners anyone that is busy and needs a professional look. I remeber seeing some franchise/business opportunity in the at home day spa arena...

If you can do good work--are customer oriented--listen to customer--get referrals this could be a good opportunity...If you are young you could save money for shop or mobile business..I think there is amobile nail business too..

I think it will take more time to get established as mechanic and the schools are expensive without getting the experience...

Keep us posted good luck
