Airgun smiths?

Are there any good airgun smiths around to work on a couple old airguns I picked up recently? I have a Healthways Western Plainsman that doesn't puncture the CO2 cartridge and will probably need seals if it does along with a couple CO2 lever action rifles that need some love as well

thanks
What lever actions?

From what I know the Heathways western co2 pistol has the similar internals as there other pistols. I have had some success fixing the other models. I need a picture of the inside of your gun to see if it's the same valve. I may have one for it.

Bye the way. I'd love to have that pistol. It's the only one from the Heathways series I don't have.
