That is an amazing goal and I wish you luck and support your efforts (obvious from my "investing" in you). Personally I have gone from putting $200 on Oddsmaker to just over $1000 or a 400% increase, and was very happy with that. But I hope that you can blow me out of the water.
On a side note, I have made a pretty good return by betting on the Kansas City Royals against ... it doesnt matter... to score under a certain number of runs in a game. I usually bet the under when this is around 8 or 9 points total. This is def a good bet when James Shields is pitching. I am from KC and love to see them win, but I also make a good return when they win with a low scoring game. Just something to think about and look at, thought I would mention it as I have made around 200 bucks with pretty small bets (about 30 bucks a game) pretty consistently this year.
