Using the bankroll of a casino that should be normally there to support any winners, and basically a guarantee of sorts that you could play here, for marketing or any other thing to grow is not really a great idea. I also do not think that casinos should be doing it themselves at all, it sounds like a lot of work and with so much they have to deal with, I do not think that it would be a smart way to handle. Best thing is to focus on what you are doing and leave the marketing to an agency of sort, that way that agency would be able to make you more famous while you focus on the casino part of the deal. Not a bad idea at all.
