How is OP selling the casino he is talking about here? has it been sold? Can someone bite at the price he wants? I don't think anyone has had any interest in contacting him to buy it yet.
Maybe, if OP would just listen to other members' comments here, there is still a chance that the buyer might contact OP immediately. How about because the price he wants to happen is a bit unrealistic and OP doesn't seem to see that?
We don't know the rest of the news because it doesn't look like he's back yet. Maybe he has found a buyer who intends to buy his casino at that price.
I suggest that if he hasn't found a potential buyer here, he can promote it via social media to find potential buyers or other places. But be careful with scammers who can cheat at any time

This is my first time seeing advert on casino sale and I am still think how he's going to sell it if the buyer can only be present online. It looks like something is wrong since op has stated it tat he intend to use the money for some family business. There are scammers everywhere and he need to be very careful when putting this kind of advert online because he can be tricked if not being very careful.
