Realistically, this project can not be done for under $xxx,xxx according to the specifics you want. Were currently working on a $xx,xxx poker project for a client that is simpler than what you are looking for. Some of the bids on this project are so low that the website would cost more to build not to mention the poker software (which is the expensive part). Unless you settle for Poker Mavens ($500) your looking at spending $20,000+ minimum for a single client type (IE just mobile, just flash etc), closer to $100,000 if you want a flash / downloadable / Mobile version. A casino is a whole other story. Each game would likely cost around $5,000, $10,000 if you want it to be good looking.
If you would be interested in having an incredible site, completely customized Poker Mavens software, website, casino (Black jack / wheel), we can help you do that in the $x,xxx-$xx,xxx range depending on what exactly you need done. We can also do desktop + mobile clients in the low $xx,xxx range.
Feel free to contact us on skype: acoinllc if you are interested in working with a serious development team, and not the typical time wasters on freelancer.
We hope to hear from you soon
