I got 751 hits. A quick look there had everything from a basic database for storing rental information w/ a front end for $49.00, to a more complex system that could be setup w/ ADO links to other databases, web display, and client terminal software.

Some of them were even freeware.

This isn't meant to knock down Matt, this just gives him an alternative.

Instead of charging 500-600 pounds for a custom written database application, he can charge the customer 500-600 pounds to research, install, configure, and train the users on one of these existing solutions.

In the end, the customer will get a much more robust application (if he does the research part right), and Matt will probably have quite a bit less work to do.
