Development of quiz based APP

Hi I want to develop an application and need someone to help with the process. I am more than capable in styling with CSS, but the actual application part is where I need help, making my structure and game play ideas real. In basic terms this is an app game in which the players use correctly answered questions (we will have 10,000 in a database) to move across a board (a little like a cross between Blockbusters and the vortex in the Adventure Game, if that means anything to you). The key element that interests me is that you should be able to play against other people with the app, wherever they are. And scores, as in wins and winning streaks, are added up on a scoreboard, therefore adding additional incentive to play. So the key elements are the 2 player game play functionality of the game itself, the ability to view and choose opponents of currently logged in contestants (the registration is just unique username, actual name and email address) with the app, and the scoring and leader board process. What we would like to be left with is text and shapes on each page, that we can then style, add logos etc. I have a graphic with a little more info but would like to hear pricing and responses before, so I only show to the couple of best candidates. We are naturally happy for you use this project in your portfolio once completed :0) and if things go well there are additions and developments to gain revenue (as it will be free to begin with) which of course you will be helping with. Would love to here your ideas and feedback.
