Selling T1 from a T3? How to?

We are having a burstable AT&T DS-3/T3 circuit installed in our new office for our web hosting services. With the excess bandwidth we see the opportunity to sell T1 and fractional T1 bandwidth the local business community. What hardware and config would we need to make this happen? Cisco 3600/7200? What cards? What other routers? CSU/DSU? How is it all physically connected?
