Amkor does hermetic packaging, but I don't know if they do vacuum. They tend
to work with extremely high volumes.

ASE Korea also does contract packaging, but again I don't know about vacuum.
They are probably high volume, too:

Advanced Custom Sensors in Irvine, CA also does MEMS packaging. But they'll
work in lower volumes: http://www.acsensor.com/memspack.html

However you decide to do your packaging, you'll probably quickly discover
that it's not cheap. For MEMS devices, in excess of 70% of the sale price
typically is spent on packaging and test. Because integrated circuits are
often packaged in high volumes at costs of less than a penny a chip, there
is an expectation that the same economies can be realized by MEMS. However,
these sub-penny packages are not hermetic. Hermeticity and vacuum sealing
requirements drive the cost up substantially.
