Wow, he does a HUGE area from what I have observered they are all hit twice a year, friend of my girlfriends lives in Badminton, nr chip sodbury went to visit could not believe she had one on her coffee table!
I done 21k via royal mail once £750 plus cost of leaflets, I reckon he does 150- 200k a year easy.
Including cost of leaflets I would estimate he spends 10k a year.
PS. Im on your patch tommorrw, dont worry I dont target it
but a girl worked for a commercial job I done asked me to do her lounge, if you like come over say hello!
