Besides that, it shows that you are a member of a long standing organisation, and I find is a good marketing tool. I have had more glances at my van & picked up more work because of it - I'd say up 10%. I even try & park somewhere conspicuous! For some reason people don't mind paying more for the work, even though mine is guaranteed.
I`m sorry, but I dont buy that, I am sure that no ex pats would have a clue who is NFMWC, let alone the the locals. They are probably reading all the other services you provide like you building work, toldos cleaning, etc,etc.
But dont get me wrong, I dont consider myself cheap, as like you I pay my dues here also, and thats not cheap, and also have liability insurance as well, but I see WCers come and go probably as they dont charge enough to start with, and realise that washing windows every day is no fun in 30/40 degrees heat for months on end.
Nope, not sold to the man with a tan
