unless you have a degree or skill that can command that much an hour, your options are very limited.not to be rude but an exotic dancer/stripper about the only thing that i can think of and that would only be limited to someone with experience.
$20 is a lot for an hour if you don t even know what you are going to do for a job.Try and make up a job yourself like cleaning homes or babysitting. Be creative think outside the box maybe try $15 a hour instead at first then over time raise the price.Or you could be creative and make something then sell it at the markets.
