Hi.
I am with T1PricePromotions.com which is a Channel Partners Network, Inc. site.
I may be able to help you with the private line you are asking about. I will need to know where each end of the circuit is to terminate. The physical locations, to include the zip codes and the npa-nxx. Then I can assist with timing, price and configuration for you.
Their really is no set price, as you may know, because private line is mileage driven. I have access also to thousands of fiber-lit buildings across the nation. Your circuit may be terminating into one of these buildings. If so, you could have service rather quickly.
I can be reached at:
