1. If there’s a problem, I’ll fix it.
  2. If you’re not happy with a fee, I’ll ask you to make me a fair offer of what you think the service is worth, and I’ll accept that. Really.

What’s a fair offer? You give me a number and some reasons for that (“it’s too much” is not a valid reason; “it was more than your quote of $x” would be a valid reason).

And let me say again, I can only work with what you give me. I know my stuff, and I’ll get it done to ridiculous levels of commitment and quality. But this is a two-way street – I can’t guarantee anything if you don’t do your part (see 5And, you commit to:).
