A2billing setup and configuration

I need a multi-point system setup and configured. We utilize WHMCS, we also provide VoIP based phone service to small business clients. We want to tie these two things together, If accepted these are the things that need to be done to achieve the first milestone. 1. Setup a2billing completely 2. ensure freepbx/asterisk work 100% with a2billing 3. ensure provided CVS for pricing is setup 4. ensure general usage (can a client sign up, create an account, pay for service, and receive said service) 5. secure a2billing if needed. Second milestone. 1. link a2billing to whmcs 2. allow clients to set up/configure/purchase phones, phone plan, and number 3. have within the client panel their information for the phone system and extensions created. 4. provide access to a user control panel for recorded calls. 5. configurable options for recording calls, conferences, and other main features of a2billing/freepbx with configurable pricing. If all goes well we will also use you to provide further setup and maintenance to the system as needed as well as support when necessary. If accepted we will provide you with a server with asterisk/freepbx installed.
