Poker Simulations - Calculate odds! (Not play)

Looking for a web-based simulator, where users can input any hand they choose and can compare the odds against selectable hands, which they may choose to show the odds given the hand were visible, or hide other hands, and figure odds as though they were playing the hand out. Must handle up to 10 total players, again that the user may select number of players. This is ONLY for the purpose of simulation and figuring odds, not for actual play! Please state whether or not your bid includes the graphic design, as I am considering having this done in house. Here's an example of what I am looking for, but I want mine to be much more dynamic... I don't want the page to reload with each change in variable. [login to view URL]
