Great answers ‘top contributors’ but none of you answered the question… What if the query was purely hypothetical or for a school assignment? For shame…
Here is what you would need to do… Get a license to operate a casino in a country where such is legal. Then go to the casino software people (supposing you have chosen one… I would recommend wagerworks, microgaming, or rtg) and buy the software they sell and a license to operate such software….
You will need a large server with loads of hard drive space and a backup system… A couple phone lines, a stellar internet connection, and a backup, and a huge amount of cash in a bank account…
You will need a way to process the deposits ur clients make, might wanna start by talking to visa and mastercard, and quicktender or neteller as well…
And then all you need are the clients… Which might be tough because the market is supersaturated… But if u are fair and honest and pay ur clients quickly, there is room in the marketplace for you…
Last of all is of tantamount importance to ur integrity… You need hardworking, industry savvy, employees; a couple cashiers, a few customer service reps and at least one technical guru proficient in cpu stuff and more specifically capable of learning bout ur newly purchased software…
good luck
