Filemaker Pro (not the advanced, just the base) runs $299 per seat.
You may not need to install FileMaker Pro on every Mac. It has a Web interface that should support multiple users while running on your Mac mini. However, the FileMaker Web site seems to describe a limit in that mode to five simultaneous users, which isn't any better than what you have now unless your seven users can trade off using the Web interface so as to not exceed the limit of five users. On the other hand, FileMaker Pro Advanced supports "Runtime Maker", which allows you to "Create standalone runtime solutions that don’t require FileMaker Pro," although I'm not sure whether that would support the sharing of data that presumably you'd want. This Web page
http://www.filemaker.com/support/prepurchase.html
mentions "Workgroup database to support up to 999 people" with "FileMaker Pro used with FileMaker Server or FileMaker Server Advanced".
FileMaker Pro Server seems to cost $999, while FileMaker Pro costs $299. So the server approach would cost less than four copies of FileMaker Pro, PRESUMING that FileMake Pro Server supports users not running FileMaker Pro. That may not be the case. However, FileMaker Pro Server Advanced definitely supports "up to 100 concurrent web users." On the other hand, that product costs $2,999, or the equivalent of 10 FileMaker Pro licenses.
This may still be too pricey for you. My main point is that there are options beyond the simple one of buying FileMaker Pro for each user.
