Lee hope things are going good for you and your closer to buying your ferrari and somewhere to park it,
I wouldn't even consider selling your leads, you have paid to get them so taking a loss and selling them do not even consider, some of your options are to make the areas you do not cover to areas you now do, send a worker further? maybe consider having one or two smaller more fuel efficient vans to travel?
do what jogpost has done and open up another unit so you now have a much larger area you can cover?
sub contract the work out and take a percentage from each clean? but then If I was booking a pryors window clean and some noddy the shiner or 1scrim bob turned up I wouldn't be happy
Lee maybe you should start your own FB group where you can be control of who is in it,
