PCP Rifle Modification in the Dallas Area

I have a Benjamin Marauder - SROD in .22 and I would like to get a HUMA regulator installed. I am not skilled at doing this kind of work, and would like to have someone with real knowledge of the process do the work, and the necessary follow-on tuning. 

Is there anyone in the Dallas area that does this kind of custom work on PCP air rifles. Thank you in advance.....DEW
 
Certain you can not do this:

Marauder Project – Installing A Regulator

Naturally more tuning than just a drop in is good, at least chrony and turn adjustment screws. For 100% maximum results you may need to change a hammer spring, even the hammer but those parts are optional depending on your use. 

Have you checked the members map yet? Many people around can and have worked over marauders, might be one near ( enough ) to you?

When poking around Dallas/TX post up what you find.
