webhosting backend

I need a webhosting backend, i already have Cpanel, but that is not enough. I need an invoice system, automated billing and account creation (fullly customizeble), server information, supporting ssl. Something like combining Cpanel and Plesk. If you are up to the job, and you could make a substitute to Cpanel, so my company can have its own control panel like [login to view URL], please put your bid. ## 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) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform Linux Redhat 7.3
