The information OP provided here are the same information from the site you also provided that means the op is marketing the site for the broker. And for the price or amount placed by the OP which $1.5m to sell the casino site is not too expenses because if the buyer is a genuine person and he handles the casino company very well with his customers, he can gain his money back within the 15 years stipulated time. But what I will consider is that after the purchase of the site, the new owner of the site will still spend enough to set up the site therefore, the seller should also consider those expenses and reduce the price.
