Hydro testing question

[GroovYChickeN 2.o]

I now own an automag! JOY! I just need to get my HPA tank hydroed. I know I can send it off to places like hydrotester.com, but I'm trying to get around shipping my tank off. I've asked around my town to try and find a place that will test it but no dice. Is there a list of certified tersters in the central Illinois that I can check out or am I on my own?

If you don't have a local scuba shop then phone around to places that deal in fire fighting or emergency equipment and ask where they get their fire extinguisher tanks hydro tested.

There is only a limited number of places so it may be that you need to ship if you're in a smaller town.
