Plumber recomendations for gas meter/line in Baton Rouge?

I’m looking for a licensed plumber in Baton Rouge to install some step-down regulators on a gas meter at my house. The Pentair (pool heater) rep is telling me that the heater is not getting enough gas to run the heater on the hot tub. I can’t get the plumber who installed the gas lines out there to see if it is an issue with the meter or something with the heater. So, I am going to assume the Pentair guy is right and install an upgraded meter. Since I can’t get the original plumber out there, I have to move on and find someone else. Does the OT have any recommendations for an honest plumber who can install these step down regulators (one going into house and one going to pool heater) in Baton Rouge?
