Thanks guys, I appreciate the feedback.
Thing is, I have a few customers who want some pressure washing done. I did recommend a 'friend of a friend' but I don't think anything came of it and now I am reluctant to recommend other people as it's my reputation also on the block.
I'd rather learn to do it properly and offer it myself.
Also like Nat says, I'd probably get a great sense of satisfaction from it. I love first cleans for the same reason.
Just like my women...the dirtier the better!
