Thanks for the input. It is their product and I'll incorporate this info into the pricing factors, thanks. I have somewhat of a spec but it needs more review before it can be considered a serious set of requirements. Time-estimate is fine. I'd rather do it for a fixed price -- the company did agree to have a term structure for compensation 15% at start, 15% at first milestone etc.
