Advice on BGP traffic engineering for classified traffic

I'm curious if anyone has a pointer on traffic manipulation for
classified traffic.
Basics, I have a really cheap transit connection that some customers are
paying reduced rates to only use that connection (and not my other
transits). Though I've considered support for cases where NSP peering
disputes break out. While I can advertise their networks out the correct
transit for return traffic, I still have to figure out how to handle
egress traffic.
I'm guessing the crux of it is policy routing based on source address,
but I'm interested in ways to engineer it to easy management and
scalability. I've considered the possibility of an l3vpn to interconnect
customers that are not requiring full routes, and possibly some type of
vpls tunnel terminated at the necessary router for customers who need
full routes.
Thoughts, pointers, suggestions?
