1st time tryin this out! Need to slim down badly

My name is josue, I'm 6'4 271lbs. Played college football and after graduating I started a family with my wife. Needless to say I put exercise and eating right on the back burner. Paying for it now and really want to hit the goal weight of 240 lbs by the start of summer (June '14). I'm not happy with my body but lack serious motivation. Exercise opportunities are slim but I will be slashing calories like a used car salesman slashes prices!

I am hoping for tips to eat right, budget friendly recipes, please limit seafood recipes lol I'm cooking for my family as well and the wife is picky!
