HI,
Do NOT pay anything up front. Business are supposed to pay you, not the other way around.
I use to work for http:
www.customloyal.com, using a telephone. Had to quit for family reasons, but they are a good company.
You can find much information on legit jobs at:
http://www.workplacelikehome.com
Just look to the left for Forums, then look for Listing of Legit Jobs.
Best of luck.
