Hi,
A CRM can be a very complex system, sugar is a CRM with years of development and tons of features, is important to make sure which information are you collecting on sugar, then, select wich features of sugar are you using, and finally make a final proposal.
I have good experience with CRM, Sugar and I am a Filemaker expert, lets talk without any compromise.
Actually I am studying a Master in Cognitive Systems and Interactive Media, I have some time available for your project from any friday to tuesday.
I am a very skilled developer although my background is in Business I am doing my postgraduate on technology, also I have been developing Filemaker for more than 10 years.
