You could do, but I dont think, that would work with a tradesman, they have to cover their fuel, paper work, ink etc, time to pay an accountant, wear n tear on vehicle, etc, I can go on, but I wont, if your talking lawns, hedges, best to look for a large outfit, that does regular garden maintenance. Hard landscapers, dont usually look at that type of work, unless they are in need of work, as you need lots of regular customers, and thats mainly summer time, which anyone can get on the band wagon doing, you dont need to be skilled to mow lawns or cut hedges.
