Using VB as a Client Database for a nonprofit

[bigr5026]

Ok, Im just throwing this out here. I recently got a gig at a non profit that does phyc services for some underprivileged children in some local schools. There are 100 practitioners and thousands of clients. We are looking for a solution and modding VB almost looks like a good idea. Im just tirekicking, but we cant afford to hire a programmer, so im thinking that going this route would be a very very good idea.

Problem is it would need to be 10000% reliable. I want something web based and passworded is always nice, so any opinions? They are currently using some alpha 5 based software from 92 or 94 or so.

So, what do the pros think?
