I am now working with GreenInfo Network and SF Botanical Garden to find a solution. I'll try and keep this updated.
Easiest way is for you to ask what kind of database they use. If they use any of FileMaker possible ODBC drivers might work for you to integrate there tables into your solution. If so you setup a DSN to there database and then you can use there table inside your solution acting almost like it was your own FileMaker Table
