"The problem is I didn't find out about the 1 hour until I accepted what I thought was a 2-3 hour project."
@Jean, when the client sent you the job offer to accept, didn't it state the weekly time limit? I've been able to see the hours permitted on all the hourly contracts that I've worked on (before I accepted them). In fact, many times I've asked a client to increase the hours before I accept the job (they do so and send me the revised offer).
If it did, then I guess I didn't see that. I probably just assumed it was what we agree.d to. Next time I'll look more carefully. I've just never had this problem before in all the 7+8 years I've worked here. Probably I missed it due to being excited I got the job.
