#1) Here's another option, GSR with OC-48 optical regenerators.

Then you're going to need facilities to house these regenerators.
#2) One advantage of leasing dark fiber is your company could implement a
DWDM solution and pay as you grow. You could add an OC-48 as you see fit by
simply adding lambdas (OC-48 wavelengths).
It all depends on how scalable you want your network, and if you would meet
these requirements for this much bandwidth.
David and Andyh both brought up good arguements for leasing from a carrier.
50ms APS on carrier OC-48 Ring.
Just my 2 cents...
