Clone of phplivesupport, liveperson.com

This bid request is very simple. I need a software created that I can sell like [login to view URL] and liveperson.com. Liveperson only offers a hosted solution where you pay per month. However [login to view URL] offers the ability to download the software and install it on your server. I want my customers to be able to download the software and place it on their server...so it has to be compatable with 99% of servers out there. I have had a version of this software created before,but it is not good enough to sell. It is mostly fully functional but in order for it to work the admin panel and the chat screen constantly refreshes. This is very annoying and I don't want to sell it. You can see the admin of this inferior product here [login to view URL] You can see the user demo here [login to view URL] The solution I want must have the features of phplivesupport including a downloadable system tray windows based interface-as well as an online admin section. You can read about the winapp here [login to view URL] I would prefer if someone has something already developed because I would like this completed asap! Thanks . ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Needs to run in all versions of Internet Explorer. Also the win app needs to run in Win 98, ME, XP
