Moving away from handle service

My institution has used handles for more than a decade and would like
to stop (non-standard ports, special server, etc), particularly as
we're now committed to DOIs.

However, we don't want to break URLs.

Does anyone know of a third party service that we can hand a list of
handle-to-URL-mappings and walk away? Preferably with a single upfront
payment rather than on-going cost.

cheers
