Are there any companies that anyone here would recommend?
For prototype work its usually easier to deal with a small local shop.
They are used to dealing with small production runs. Contact them by
phone and then go visit their shop so you can explain (in person) your
design requirements and answer any questions they may have.
Developing a good working relationships with your local machine shops
can be invaluable. Treat them well. They can really help out, especially
when you need something in a hurry.

I work for SAIC (but I don't speak for SAIC)
In addition, you might try a local university with engineering or
materials departments. You might get a more specific suggestion if you
tell everyone your approximate location.

Here's a facility I've used with success:

I don't know if they do TiN, and I don't know how they handle small jobs
for people outside the university. And they might be half a world away
from you.
