Business form for window and door business

I am looking for a quote form for my window and door business that will follow a specific layout. I would like the design of the form to be intermediate. The form should be able to capture necessary information such as order details, terms, and customer information in a professional way. There should be room for both digital and manual signature. Additionally, I would like to be able to have the option to adjust the form as requested by customers. All this should be done in an efficient way that is easy to understand.
