Owning and hosting a Online Bitcoin Casino is not a $400 investment in a possibly pre-configured {full of backdoors} online script.
A online casino needs a 100% secure environment, to protect it's customers money. These pre-configured scripts are the reason why these sites gets hacked.
A decent copy of a well known online casino, will cost you in the region of $30 000 to $40 000 {This is without the Bell's n whistles} I have asked around.. and this is the starter kit.

Then you need a decent marketting budget, to compete with the other 1000's that are out there already. If you cannot even afford the $10 hosting fee... what will be your chance for success?
