doron, i think your idea to be the only wfp window cleaner guy in isreal is a great idea.
I use a scudo van (fiat), many use vivaro's (vauxhall), one forum member uses a quad bike.This last, the quad bike is also a great marketing tool because it creates interest and is a conversation starter.Let me say though, that your plan of using a camel to work the round is simply brilliant.
Not only a great usp, but also a good tool to do the tops without too long a pole.Not sure about the name- hump window cleaning- but i'm sure the future is very bright for you.Best of luck.
