Live Person kind of PHP solution

I need a solution like Live Person. See: [login to view URL] [login to view URL] [login to view URL] [login to view URL] All the standard features plus some that I would define in addition which would customize it for a specific industry. That customization would consist of one extra field on the client side and about 10 extra fields on the administrator side. Sorry I can’t say more right now. It will have to support customization on both, client and administrator side through some kind of templating mechanism. It doesn’t have to be too elaborate. Feel free to ask more questions. ## Deliverables I need to have a complete and exclusive rights to the script. We would have to sign an NDA before the start. Script will have to be easily installable for my clients that purchase the script. It will also have to enable me to host it as an ASP for my clients which means integration with payment processing system, reccuring billing, generation of the code that client would have to place on his web page, etc. ## Platform PHP, MySQL
