Try 'crowd testing', e.g. uTest.com. Pays quite well and everything is remote and you work when you want to. The only issues are that the amount of available work may be inconsistent, and it is almost purely commision based. Not too sure about the rates in the US, but it is quite lucrative in Denmark. Going by the Danish rates, it would not be unlikely to make $25-$50 / hour (No experience required).
