Thanks Jeff for your time and answer
Actually, that's what I've been doing all along. I propose 3 samples and if none of them are accepted, I offer to do a fourth one, but this time entirely to the specifications of the clients (colors, style etc) Until now, all my clients have been happy with one of the first three. But now I have two problems : one is a client who after the 11 th (!!!!) sample is still not happy, and the other one is a new designer we got on our team. This designer wants to be paid extra after.... the first sample! So I'm trying to navigate between the two and I was wondering how other web developpers handled these questions...
Thanks again
Patricia
