US West !nterprise sells such a service, only for frame relay connections.
If you are in US West territory, or in a city where !nterprise has service,
then they can provision it (they are also the only carrier so far that does
not tarrif or sell Frame Relay based on CIR, simply port speed and local loop
only).

Operationally, I have typically experienced under 30 minute FR circuit
turn up times, from when I call the engineer.  My current employer is not
a US West customer, but we will be in the future.  Their engineers also are 
not just familiar with the parameters you need to know to provision/configure
just Cisco equipment, a situation I have experienced with other carriers at 
times (I've been told, "What do you NEED to know the DLCI for?", carrier
name with-held).
