What is certain is that if there is someone who wants to work with Op it will only make trouble for himself because Op has been limited to every Sportbook which indicates suspicious activity.
Maybe he will offer something that is very profitable but the risk to his gambling account is also high when one day it can be banned by any Sportbook.
I'm not really sure if Op really does bad things on every bet in the Sportbook but for sure this is definitely something suspicious and not something to do.
It is better to avoid those kind of offers, I know there are many forum members which dream of becoming profitable gamblers and in fact there are a minority of them which can do it thanks to their immense skill in a game like poker or sports bets, but the profit margins are on the low side and having to share those benefits with someone else while you take all the risks does not seem like the smartest idea to me, even if the methods of the OP to win were legitimate.
Involving third-party services that include paying of fees of a percentage in winnings is not something that should be encouraged, and for the ops to state that he needs pm shows the hidden possibilities that could leave those that will contact him uncertified in the long run.
I don't think it is worth the risk either and I believe with luck on your side, one could easily win some relatively small bets in the bigger one it all depends on the risk level of the individuals involved.
