i wish i could get 300 x £20 jobs, i think it is a good idea, u just need to know what each house is going to cost to do and make the jobs worth while, u need to know what all the charges are
fair enough you might not make a lot on the first clean, but its getting you to custys who want a wc, then it is up to you to get them as regulars, on normally prices
to me it is the same as having a canvessor, you aint goign to amke money on the first clean, its the cleans after when you can fly around that you make money on
