Thank you for your post.
You might search around the Made for FileMaker for pre-built solutions that might fit your needs. Another option of course would be to hire a consultant to create a database customized for your needs. You can find the consultant search here: FileMaker Consultants, Data Consultants, Database Consultants
I'm also going to move this thread from the Community Feedback, which is for input on the Community itself, to the Discussions page where you should receive more views and advice.
