Simple PBX with VOIP connectivity.

I have absolutely no experience with this, so I will need someone with experience setting this up. I would like someone to setup a pbx (or other solution) with the following features: Record all incoming and outgoing calls automatically. Have a call que which keeps the caller on hold and listening to music until the next available operator is available. Have a standard greeting during business hours, and a different greeting for non business hours. Prefer to use VOIP service as the cost is lower than analog. We are a very small company and would like to show the customer a more professional telephone system. Only experienced people please. Must be able to talk on Skype
