Medical Database Software Software Development?

Software development? - medical database software

This is a general problem that must be met by people with experience in the development of software applications. I wonder, on average, how many people need to develop a fairly deep software application that is connected to a database to. I ask because I, if a company wants to build an application such as WebMD, not the medical center site miracle. This means applications from hospitals and clinics, every application they threw into the appropriate format for the appropriate insurance payer, then 837, then uphill to the appropriate authorities. They also have custom reports for what / where / when to show the claims lapsed. In addition, it would mean a connection to some 1,200 insurance payers. This would be the database of automated software applications and a variety of amenities that make the FTP automatically. I am looking for an entry in the number of programmers and networks, people need to develop this type of information. My guess is at least 20 What is this?
