Tell you what I do and that's to have one week allocated for the 8 weekers and keep 'em there. If one or two don't get done, that's tough, and if it goes on for a couple of time I drop them.
This refines the quality. Yes, it loses money in the short term, but the quality is high.
This probably only works with a close tight round, not more than two miles diameter.
Every four weeks I know I have a week off for myslef or can fill it with insides or gutter cleans or pressure washing or diy jobs around the house etc.
