I have bid on a job and have given the customer a verbal quote. I gave him a copy of the design and he informed me that I was $30 cheaper than the other company giving a quote. Made me feel good because this is my first and I really did not know if I was in the ball park or not. Well I need to put together a written proposal and just don't know hoe to start. I give lots out for commercial maintenance but never for a new irrigation install. Can someone post for me a layout? Do you list all material needed and give a breakdown, material, permit, labor, etc.?
