Need help meeting Rollover to cash out 30k from online book

Gentlemen,

I have met 20k of my 40k Rollover and am getting antsy to meet the rest and get my money out of this book.  Here is a plan I have devised, tell me if my line of thinking is correct. 

If you take two games ( Mich St. vs. Louisvile and Florida vs. Marquette). And then a third game tomorrow for a hedge: Kentucky

You parlay each side of those games together:

1. Florida and Mich St. and   Kentucky

2. Louisville and Marquette  and Kentucky

3. Florida and Louisville  and Kentucky

4. Marquette and Mich St. and Kentucky

Play those even for 1k each:  3 are guaranteed to lose unless by fluke it lands on the number.  So you are down 3K, The 1k you wagered on the one that will get to tomrrow with the hedge is worth ( 1k that you wagered and 6K payout) so 7k total. 

How much would I then hedge to make sure that I have wagered as much toward my rollover and lose the least amount of money? 

I cant wrap my head around this and your help is greatly appreciated.

I don't like the strategy. Here's why...

Kentucky might lose and you are out 4k. If you want your money back just pay the juice on straight wagers. Depending on the book might get a reduced juice 5% friday or something. Lay the same amount on both sides and you pay 5% instead of opening up yourself to a 4k loss. 5% of 20k is only a grand, and 10% is only 2 grand. I'm assuming you are up 20k plus based on the rollover requirement? I'd put the books limit for that sport on a game so maybe you move the line and even catch a middle.

Good luck with whatever you decide

Mike

LOL Thanks for what?  Blowing $10K?  I thought most books only count straight bets toward roll over?  IDK, but I would check first.
