Looking at what some people charge I would say not. But the new customers i'm picking are getting charged more so if I had enough then perhaps.
46 weeks a year (allow for hols, bad weather, sickness etc)
Aim for £800 turnover per week
£800 divide by 5 days per week = £160 t/o per day
£10 average for each customer.16 per day. 3 custies per hour. 5.5 hours actual work (plus travelling).....part time work
Also leaves time for extra's like conserv roof's, gutter etc etc
