This seems like a disaster waiting to happen. If the owner of this site cannot fix basic things like setting a page title from "Undefined" and knowing the the correct spelling for "Roll" is not "Rool" then you should have zero faith in their ability to keep a casino online. Either you're going to end up doing all the hard work to turn this into a prosperous site, at which point it'll be sold or your admin abilities get removed, in the "best" case scenario. What's more likely to happen is a real or staged hack will end up taking place after a small amount of depositors have placed a fair amount of money into the site. Even if it did start to take off, it's going to be the target of relentless campaigns to take the site down and this owner doesn't strike me as having the financial resources to fight back.
