FWIW, if your multi-millionaire friend loses a game, he will be fine. I recommend to just post the play and quit with the hype...It more than likely is drawing attention you won't like in the long run including bashing. You are basically giving an unrealistic expectation and any loss early on makes it seem like the whole thing is a joke. You have virtually created a scenario where a record of 10-5 will look like a losing outcome because of the boast.
Keep in mind if you make any attempt to sell these you will be asked to post in Site Promotions only since you are not a sponsor.
Welcome to the RX and good luck beyond that.
