New to MS Dynamic

I am new to Microsoft Dynamic. I worked as ERP Consultant and Analyst of an Open-Source Software for 3 years. Recently my company interested in Dynamic AX and wish to convert our in-house software into it. Our business are specifically focus on Healthcare sector. We are more eager to implement our own solution rather than rely on Microsoft Solution Provider.

I am in charge of finding as much information as possible before we make the switch. Please help, thank!
