I haven't done one in New Orleans, but B Business Solutions has a few casino shops, one up in Connecticut that I do regularly- I believe they have a few other casino clients, too. They're relatively easy, pay well enough (money-in-your-pocket) and have a generous gambling reimbursement. They also give you $20 to buy a snack for yourself while in the casino, because part of the shop involves drinking the free liquor given out by the casino and, presumably, they don't want you drinking on an empty stomach.
The only downside to the shop I can think of is that there are certain kinds of table games you have to play and the shop requires them to all be different; this sucks because sometimes you cannot find the specific games, you do find the games but they have a high minimum so that you won't be able to spend the requisite 20-30 minutes at the table with a reasonable amount of money, or you're just new to that specific game and are uncomfortable playing it.
Say, for instance, you need to play four card poker, black jack and roulette; you can't just play multiple games of black jack at different tables with different dealers, you must search the very large casino for roulette and four card poker tables as well. And you're given a generous gambling reimbursement but that's assuming the minimum bet is $5-10. If you can only find roulette tables with $25 minimum bets, you're either going to have to wander around for hours hoping another one with a smaller minimum opens up or show up, be weird and bet really slowly to fill up the requisite time.
