I have built several itsps from the ground up. They range in size from a small satellite-based carrier with 200 phones to a CLEC sized system with several thousand users moving several million minutes a month. I can work with you spec out servers, build and install operating systems, build applications, and get everything going to the point your first customer makes their first call.
