btw I plan on making a poker site for me too. Tell me are you using wrdpress for it? and what about the pictures, you've got a professional graphic designer or are you doing it all by yourself?
Instead of buying some casino pbns or something like that, hire a decent social media expert. Make some viral content and go viral. If your ad is engaging on social media people would quickly rush in. SEO is too mainstream these days. It's gone to be honest. Rely on social media
I guess to get the engaging visitors for your casino website, Google or organic traffic shouldn't be your main concern. you should consider traffic from social media like reddit, stumble upon, tumblr, facebook, twitter etc. That way you can get around thousands of visitors on a single day
It is known as the Seoclerks or seoclerk. Don't remember much. Just google it and you will reach it. Also they had a forum so you can asl there. Hope you find someone
