i agree with steave mate, also like steave says about "partners" try and get your self 1 down our loft there is three of us, 1 works shifts, 1s a cab driver, and last of all the handsome 1 "me" is a sparky and all works well with timing. 2 of us r all ways there we take the training in turns and all just muck in when we clean the loft, my advise to any novice of someone starting up is get your self a partner oh 1 more silent partner i forgot to tell u but shes part time and thats the wife she only gets involved when we need here to take the blinds off in the morning for the darkness.
