Are there any legitimate work from home business on the net?

Hello everyone, I’m trying to find some legitimate work from home business that is completely 100% free to join and become a member(No Credit Card Required).
But if there is a work from home business that requires some kind of pay to join or become a member I wouldn’t mind as long it’s legit and it pays well. Please answer only if either you have gotten paid from the home business site you are recommending. Or you are 100% sure your home business site you are recommending is legit. Thanks very much.
