I'm wondering why you are targeting oaps and women on their own. If you are serious about getting into the gardening business you cant afford to limit your client base. Continuety of work is the answer. �10.00 an hour is OK for a bit of part time extra money, but 8 hrs per day x 5 days per wk = �400 pw = �20,800 per year. Unfortunately you will not work every day, so when you factor in holidays, bank holidays, rainy days, short winter days, transport/fuel/equipment and maybe VAT etc, you will see why 'professional gardeners' charge more!!
