Why not open an announcement here on your casino? This is the best way to start marketing and branding your casino. Once you do that, it will be easy to get promoters or affiliate marketers to promote your casino.
Another way to establish your reputation is to launch a signature campaign. There are many managers here who can help you establish your brand.
It seems quite amateurish, and it doesn't offer anything that any other established casino doesn't already have. I wouldn't give him too much attention unless he makes an effort to prove that he is worth it, and he has to do much more than what he wrote here.
btw. A signature campaign is not the pinnacle of marketing, why many people only see it in a narrow way.
