AMD makes a few chips that might just be what you're looking for.
They're perhaps a bit faster than needed though.
Look up the AM7968 and AM7969, a.k.a TAXIchips.
The former accepts a parallel word which gets serialized and sent to
the latter, which convert it back to parallel format. Bit rates up
to 100M bits/s.

Cost was around $35 per chip, when I last looked.
