If you can get Carol Doak , the queen of paper piecing, that would be great. Or Carol Bryer Fallert.

Or Bob from Superior threads , he has so much info and is a great speaker and everybody uses thread. If you think you know everything there is to know about thread .. well Bob knows more than I ever thought I knew.
Another awesome choice would be RaNae Merril ( I think she is in the NYC area).
