@eaglescout88 Seeing your comment of scaling to $5m w/ 500,000 homes to target, you're going to need to expand beyond just gutter cleaning.
Gutter guards are a high margin service (if you price appropriately - pressure washing guys rarely price correctly). Same goes for either subbing out or buying your own gutter forming equipment. There's a reason you see it more as an ancillary service than a specialization.
On my home, my gutters cost me $650 to have cleaned each year. If your bread and butter jobs are $150-$250, you're likely competing on price, which means the lower end of the market. How much time, all in, do you have on a $150-$250 job?
(I consult for approx 70 companies that either specialize in or offer the service.)
