That is exactly the link I was going to share with you.
I don't actually use a quote sheet in my own practice so would defer to the Microsoft template.
I think, in concept, as long as you're clearly articulating back to the client what it is you understand the job entails, how much you *estimate* it will cost, and an estimated time frame for delivery of the completed project (or a deadline if agreed upon with the client) then you've got the bases covered.
Adding a bit of text about what the quote is and any additional details on how you will complete the project (if necessary) all capped off with your logo, tagline - or company letterhead - would be a nice touch as well
