Best way to supply colo customer with specific provider

Hello all,

Being relatively new to the colocation business, we run into a fair number 
of issues that we've never run into before.  Got a new one today, and 
although I can think of kludgey ways to accomplish what he wants, I'd 
rather get some other ideas first...

We just had our first customer that's requesting bandwidth exclusively
through a particular provider of ours (Cogent) at less expensive pricing.  
The money people here are up for it, but obviously, they want to make sure
that he's confined to that Cogent connection.

So now of course we're attempting to figure out the best way to do this, 
and I figured that rather than reinventing the wheel, I'd check to see how 
others accomplish things like this.

The way I can imagine doing it is by using route-maps to steer all of this 
customer's traffic out the Cogent pipe, and modifying our BGP 
announcements by AS prepending on whatever block or blocks we set aside to 
be "Cogent-exclusive".

Again though, this seems to me to lack a certain amount of, for lack of a 
better word, "grace".

Any other suggestions?
