Ask HN: Would you share your sales proposals? Do you have a standard template?

Dear enterprise sales folks, agencies, and freelancers:

The most effective agency I ever saw closed 50k deals in 2 hours: 1 hour to have an initial meeting and 1 hour to customise a thick and detailed deal doc. Do you do something similar?

What sort of proposals do you give to clients to nudge them over the edge of the big deals or to arm them to convince their bosses and budget holders? Do you tweak a standard doc or go all the way from scratch? What does it look like? Would you share some that have been particularly effective or ineffective?

Thanks <3
