Your provider won't do QinQ for you? Have you verified they support
the appropriate MTU for you to do your own QinQ under their tag (at
least 1502)?
As far as equipment, most Cisco kit from 3550 on up will do QinQ.
Other alternatives would be to light it with routers and do EoMPLS or
VPLS, but it'll be more expensive than just doing QinQ but potentially
more scalable/stable.
