Asterisk Party Line system

We are looking for somebody who can help us design and develop a party chat line application with integrated account balance tracking and multiple operators using Asterisk PBX + Addons / AGI Scripts.

The flow should work something like this:

We have operators and callers. Callers will be identified by their CLI when they call into the system. If the caller is a registered user and has enough funds, an available operator will be selected and the caller hooked up with the operator. When the funds run out, the call has to be terminated. If about a minute or so is left, a jingle should announce to the caller that their credits are about to expire.

Topup should be possible via IVR (voucher) or online. We will work out the interfaces for that. Your software can just integrate to MySQL for checking/updating the callers credits. To give you a better idea, we are looking to build something like this here:
