you want to work on your jeep?
why not find a mechanic jobs locally? not in any shops but just post your own ads as a "drive way" mechanic. Small, simple things but also ones that can pay well. You would need to manage your income/tax returns but that's a skill you need to pick up eventually anyways.

Golf courses seem to need physical labor jobs over the summer but I don't know Ohio... are they big on golf there?
Is there an old car lot? not to sale cars but recycling them. You'll learn more about cars from people there if you really are interested in that.
There's more openings for outdoor jobs that aren't "clean" like landscaping where they don't really get dirty outside of digging a hole...
