Startup Idea : Daily Fantasy Sports With Friends

Currently daily fantasy sports are played in a public pool. People who aren't that good play against experts, which is good for the experts but not for everyone else. Would like to create daily cash games where you can play against one or multiple friends you invite to the game. Would also like to create a season long format were groups of friends could compete for an entire sports reason, with a leaderboard, and season-long prizes as well as the daily prizes.
