She doesnt want to pay me?

3 years ago i went to California to visit my family. While i was there my uncles wife was looking for someone to babysit her baby and to clean up the house because she was pregnant. So i told her i was gonna do it but she was gonna have to pay me. The deal was that i was gonna be living at her house, working 6 hours everyday. And she was gonna pay me 13 dollars the hour. So i started working but she just payed me like 60 dollar every week but i couldnt do anything because we were living really far away from town. Then after 4 monts of working like this she fired me because i told her i wanted my money.... she stills ow me 11,000 and she says she wont pay me, what can i do? Ps i have proof that i worked for her
