You need developers to build such a decent gambling site, this is the easiest way I can suggest.
Also you can take courses like Computer Programming (Web development) if you just willing to learn and happy to understand everything.
Why would anyone have to undergo the stages of taking a computer programming course just because hes interested in building a gambling site? I hate when people stress themselves over issues money can easily solve. Anyone that is willing to build a gambling site should be financially stable to be able to make this decision, so its just better to pay a software developer for this and expect to get a good job.
I suggest that the OP would have to be prepared to spend money, especially on advertisement. Its one thing to create a casino site and another thing to drive traffic down, so he should be ready for the challenges ahead.
