Slightly above is good. As you move up in your career, the thought is, you get what you pay for. People don't brag about how cheap their lawyers and accountants are.

I would investigate to find their emails. Linkedin, google. Figure out the pattern of how they set up their emails. First initial, lastname @ whatever.com. Say what you know its a little unconventional but you wanted to reach out to thank them for their time, explain WHY you're perfect for the role. And thank them again. I've beat out 360 other candidates just by going the extra mile in the interview process.
