That can be done. If these are mono, two-track tapes, the most
cost-effective technique I apply and there is no degradation if the
tapes are not using noise processing, is to record both directions at
once and flip one side in the computer.
Double speed can be done on any of the high-end recorders that
provide adequate "handles" (The Studer A810 or A820 have a very wide
range and the Sony APR-5000 is close, but has a few quirks for this
type of unintended adjustment) or on any machine if you play a test
tape at 2x and slow it down in the computer and draw the inverse
curve to make it flat--storing that as a preset.
If you do double speed and record at 88.2 and then slow down to 44.1,
you'll actually lose little, especially if the originals are 3.75 or 1.88 in/s.

There are many competent individuals on this list who could undertake
your project. I'm re-compiling my taxonomy of media which lists a few
places that can help get the job done for you. Of course, I would
like the opportunity to propose on your project as well, as this
falls squarely in my area of specialization (tapes from 0.150 to 1 inch)
