add the results of different forms

Hi,
I need create a full width page, with estimates forms, for constructions sector. (http://www.costruzionimartini.com).
So, I’ve much forms for much items, and I need 2 thing:
1. is it possible to combine the results of different forms? (adding id-name)
2. a single form is large 394px. Isn’t possible have it large like the page?

thanks
