I have a freelance question.
I am about to do work for a very large corporation on a freelance/part time basis. The contact wants me to give him how many hours a job will take? I really don't like to give that since I am not sure. But I can say the job will be fairly simple. It's a Flash job and all I have to do is replace the dates in the Flash file.

Any suggestions on guessing how many hours a job will take? Also, do freelancers give a minimum hour rate? In other words they won't take on a job for less than 4 hours?

I hope I'm making sense. It's early.
