Asterisk in a ACD configuration

Hello All,

I need to set up an asterisk server for an ACD application all on VoIP/SIP. A call comes in SIP and transferred to a SIP phone that is registered with Asterisk a second call is send to a second SIP phone etc. On busy or no Answer the call is transferred to the next SIP phone and when all lines are busy or there are no answers the call is put in a queue with music/message on hold until a line becomes available.

I would like to know if someone has already done this and can configure it for me turn key. I WILL PAY FOR YOUR TIME AND EFFORT. Please write me back at if you can help me and are interested.
