thanks for the help guys, its given me food for thought, i think i will give here a couple of options regarding the level of the clean.
She is a plymouth brethren, and in my experience they are tight and like to haggle, i get the impression she wont want to pay too much, so giving here a couple of different prices for different levels of work might help, plus if she only wants the panels cleaned and nothing else it will be fine by me, i hate cleaning roofs
