Does anyone have experience with pool routes - particularly in Texas?

Looking to start a pool cleaning business and acquire a route in the Texas area, preferably North Dallas. Would love to connect with someone who has experience in the space to discuss pricing, growth, strategy, etc. Also, I've been told that having a reliable repair tech is essential as repairs are frequent and necessary - is it possible to find reliable subcontracts / third-party repair techs and not have one on staff?
