In an area where the average bung is £6 and thats 4 different companies i know of inc myself who price at that,why charge that little??
With overheads i have/most have couldnt do that,hell 4 of them at 3.50 is 14quid an hour,after diesel,insurance,tax,mot/repairs,public liabilty,water,detergent,gear etc etc and all the other outgoings-you would be working for minimum wage guaranteed.Whats the point?!
