Essentially, I need a website that can be used for one-on-one chat sessions and incorporates a billing system for clients. The chat system can be any language, really, as long as it alerts the webhost to an incoming caller.
Clients should be able to register and input personal information (billing information, specifically), while the webmaster should have a control panel to set a per-minute rate.
Using a CMS as a base is fine. The site need not be complicated and as such, sometimes simplicity is best. A per-minute billing script can be used, the chat software need not be programed, just one incorporated. The most /important/ ability that the chat software needs to have is to alert the webhost that someone is trying to contact them (a pop-up or such). It should be entirely web-based.
Please only post serious inquiries. We are hoping to keep the cost of the project down, though hoping for it to be completed within, at most, two months.
Thank you.
