As the host, it's your responsibility to keep the game stocked with new players and fish. Aside from inviting the usual friends and coworkers, you can head to your local poker room. There, you can sit in an Omaha game while you and your friends talk about the game with other players. Depending on the house, they either do not care or will throw you out, so know before you speak. Anyway, this is how we keep our game stocked with new money. We've got a list of 20+ players to draw on. Seems to work. Good luck.
