Thank you for interview, but reject offers

Sample 1:
Dear Andy,

It was a pleasure to meet with you the other day. I was anxious to learn more about your firm and its plans for the future.

Unfortunately, I do not feel my qualifications suit the VP of Marketing position at your form. As you know, I prefer to stay close to home and will not be able to travel as extensively as the position requires.

Nonetheless, I truly appreciate the opportunity to have met with you and I sincerely wish yourself and your firm the best in the future.
