Went with the honor system. Cheap, works. If someone abuses it, their privileges are reduced. No cost at all.
I've seen folk hunt for that unicorn for years. The honor system works very well.

Good Morning/Afternoon/Evening everyone,
I work with a non-profit organization that provides transitional housing to homeless veterans. One of the services we provide is internet access from our computer lab. Per our Executive Director, our clients are allowed to use the computers for email purposes, 15 minutes per day. With approval from a client's case manager, they may be allowed a longer period of time and/or to visit other sites (e.g. job searching, applying for benefits, etc.). Currently I have a net cafe software I can use for time limits and the routers setup for whitelisting email websites. What I am looking for is a software that will help me control both of these restrictions as needed. Preferably something that is either freeware or relatively inexpensive as funds are limited. Any help is appreciated.
