Your name, and the company it is for.
A sentence is plenty. Who buys it, and roughly what it costs them.
The site in your head. What it has to do, how it should feel, anything you have seen that you liked. Rough is fine. This is the part I am most interested in.
Which package fits
A guess is fine. I will tell you if a different one makes more sense.
Where to reply
An email address. A phone number as well, if you would rather talk.
