have you got much work at the moment?
you say your going to leaflet drop,but if you need the work you should be knocking on doors instead,iv only been going for just over a year now and so many times iv had people ask me if il do there windows and i have dropped a leaflet through there door few months back so they dont work anywhere near as good as door knocking,
personally i found that posh estates are harder to get new work as it seems window cleaners target these areas for a nice place to work so dont rule out the cheaper parts of town,this could help you build your round quicker,just my opinion tho
good luck mate
