Creating a Very Basic CRM



I have the need to create a very basic tool for tracking the interactions between 12 internal employees and 80 external doctors who we work with. This seems like a mini-CRM (Customer Relations Management) tool, but is far more basic as it doesn't worry about sales and such, so many of the sales facing CRM's are way overkill. I just want to track each of the 80 doctors contact information and then an associated interaction diary when anyone has a meeting with one of these doctors (there could be several meetings with any given doctor over time).

I've attached a an outline of what I'm seeking to this message.

I would appreciate any advice you have to create this!
