I don't think anyone wants to sell a well-run casino. A good business is worth its weight in gold, this price cannot compete with that.
That's why business man exists because of business. Any established business can be sold by specific price, negotiations, etc. The reason for selling the casino is considerable too.
Actually buying an established business is a win-win situation. As it is already established its name and already making profits. If the new owner can make the business more competitive after the ownership takeover then it will generate more income. But the question is if someone will buy it for the asking price.
