Hi, so I've come up with a plan to take all English Premier League Fifa 14 player stats and come up with a way to generate the best possible fantasypremierleague.com team

Basically from a pool of 600 players who have 1 of 3 positions, Defender, Midfielder, Forward, I have $100m to spend on a team of 5 Defs, 5 Mids, and 3 Fors. I have assigned a price to each player.
I first want to filter out the players with <10 appearances this season and players with no price. Then taking the remainding player stats from Fifa14, generate a total stat number by adding and multiplying the player attributes.
Finally I want to find these 13 players, not exceed my budget, and ensure that I only have a maximum of 3 players from any one team.
Tough job I know, I was just wondering if you could point me in the right direction as to the method using RM.
Cheers
