Looking for Hermetic Sealing Vendors for Glass and Exotic Metals?

i work at a company that outsources Hermetic Sealing. i was wondering if anyone knows of any vendors that would be able to do glass sealing with exotic metals?

If it's okay to ask, what metal are you dealing with? Also, what leak rate are you fighting (i.e. compressor, semiconductor packaging, vacuum instrument...)?
