We have seen small ISPs get LibreQos running in under an hour, which includes installing ubuntu. Configuring it right and getting it fully integrated with the customer management system takes longer.
We're pretty sure most of those ISPs see reduced opex from support calls.
Capex until the appearance of fq_codel (Preseem, Bequant) or cake (LibreQos, Paraqum) middleboxes was essentially infinite. Now it's pennies per subscriber and many just a get a suitable box off of ebay.
I agree btw, that how to monitor and scale is a learned thing. For example many naive operators look at "drops" as reported by CAKE as a bad thing, when it is actually needed for good congestion control.
