tl;dr -- fiverr 1. Compose tactful email text explaining the bet. This is optional if you don't care about tact or a potential negative impact on your or your company image. 2. Go to fiverr and get a person or three to find teachers, administrators, and students who were at the same high school around the same time. Have them send the letter you composed to these potential teachers, staff, and peers. Track with close.io. 3. Get answers and try to confirm results. 4. With new data, iterate text of email and/or task request for fiverr if appropriate. If you are skilled at chatting up gatekeepers (many sales folks are good at this), then you can call the school admin, explain the situation to her, and the answer would be yours in a few minutes. There are some other options that are of questionable legality and/or ethics, but I will stay away from those.
