Tips from anyone in the pool service industry?

I'm doing fractional accounting/finance work for a buddy who owns a pool biz here in the Dallas area (currently residential, not commercial). He wants to expand via acquisition. Problem we're running into is that it seems the online pool broker websites all have opportunities where the average revenue per route is much less than what my friend currently charges (which would have operating at a net loss on those acquired customers). Wondering if anyone is familiar with this space and what options/opportunities there might be for my friend to explore. We are starting to do cold outreach to other local pool co's as well, and open to other ideas.
