It was 24 hours for one concept. When doing a project, how many of you develop only one concept for a client?
If I quoted this project, I would show a minimum of 3-4 concepts, have the client choose one to refine and finalize. The refine anf finalize portion of the project would eat nearly all of the 24 hours and I would probably add anouther 16 hours for the concept generation. I think 40 hours total would be more than fair.
As for the rate, $50/hour would be on the low end for the US/Europe and on the higher end for eastern Europe/SE Asia. Depends.
