ISO Plumbers/HVAC to refer business to me for MONEY!

I'm the owner of a locally owned pest/termite company just outside of Covington. Would love to find a few plumbers/HVAC techs. that are interested in referring leads to me in exchange for a referral bonus. In addition to standard pest and termite control I also install insulation in crawlspaces, install moisture barriers, and remove debris from the crawlspace. If you do a lot of repair work in crawlspaces this could be a huge opportunity for the both of us. You're already down there, might as well get paid a little more for it! Looking to find someone today if at all possible. Thank you!
