I would second that.
I know someone at AZCOM who contacted a DO from the phone book and called and said, "I am applying to a DO school and need a letter from a DO". Went in and talked to the DO for about 15 minutes (he asked him questions about himself and why he wanted to be a DO, etc). Then the DO said, just send me a listing of where you would like these sent. He was accepted to more than one school.
