Call Center

I need a call center, that works online. This call center needs to work like a searching tool too. Its works like this, its a web site that only people that have a username and password can enter. There has to be one administrator that can be able to look at all the info. The website receives peoples information through the internet and the call center calls those people with that information(calling people by phone I mean), then we help those peoples to search for schools by using zip codes. I have examples of it through another web site that does it but i will show it to the coder I choose. If you have any questions fill free to ask.
