I imagine most of the casinos advertised on this website have been selected by Ken because he thinks they're reputable. My advice is to try and pick one with a nice bonus for your initial deposit, such as intercasino.
On the idea of making $250/week I recommend two things. First, as I stated above find a casino off this site with a nice bonus, second, find a job that pays at least $250/week because you're not going to be making that at a casino. If it was that easy don't you think everybody would be doing it???
