thanks Ewan, the harris pole is great for residential work and has lasted longer than carbon pole i used to have, and no I wouldn't use it for commercial work. I can certainly do my numbers and my wife is a fully qualified accountant so that might help if not!
i was just looking for tips at getting started with commercial contracts and the best way people have found to get in with companies and if anyone has any templates for leaflets or letters, and also do you guys charge more per window for commercial work, i try and base residential work at £1 per window.
thanks again pal
