Conferencing into a Call Queue - Please Help

I basically need two people to be able to call my Asterisk box and be placed into a queuing system. Once someone answers from the queue, I need all three people to be able to talk to on another in a three way calling fashion.

I was thinking that I could have the two people call a conference extension and then that conference could be forwarded or transfered to a queue. Once the queue answers then all three can communicate with one another. If this would work how could I set this up?

If anyone has any ideas to make this work, that would be wonderful!
Thank You.
