I agree that this should be a brief match.
One game can be pretty high variance and not prove much. Blunders do happen.
A 5 game or 7 game match where the time control is G/45 or G/60 would be a lot better than just one game.
Also like other people asked, who chooses color (random?) and what happens to the bet if the game is a draw?
Welcome to the chess forum Allen, and all the best with your journey up the mountain of chess!
Writing that, makes me think of this book cover art:
Disclaimer: not a book to get you ready for the match, this one is probably for 2000+ (or really ambitious 1800+) but I think it fits the "climbing the ranks of chess" image pretty well.
