Paul,
Glad to here you are not giving up.
May I suggest two things to you.
Get a part time sales agencey in Direct Selling to peoples home that provides the leads and you do not have to travel far. Not Network Marketing. You then sell your Carpet cleaning service once through the door. (Secret of the door)
If interested pm me I get no % recruitment bonus etc just trying to help.
Two try telephone canvas We achieve one or two jobs for every hour that we do.
I live in a assett rich low wage area. However pennsioners are usually cash rich due to selling properties in Chelsea, Wimbeldon , Sevenoaks, , Romford, Watford, etc and moving to this area.
