Hello Dustin,
You might be able to do it yourself.
Have a look at the lensfun site, <
http://lensfun.berlios.de/calibration/>
which provides a tutorial.
Having a calibration in the lensfun database is probably the best
approach, although you will need to initially manually add your
calibration to the lensfun database.
There are tutorials on using hugin,
<
http://hugin.sourceforge.net/tutorials/calibration/en.shtml> to do the
calibration. Hugin allows you to save and load a local calibration file.
There are a number of other tutorials on using hugin to calibrate a lens.
Have a search, you might find one of those explains it well enough for you.
The other tutorials on the hugin site should help you with the stitching
process.
Cheers,
