Betting Exchange Arbitrage Bot

I am looking for a prog to uncover arbitrage opportunities. I want the prog to run on multiple exchanges, i.e. betfair & bedaq. The prog must search for standard arbs, i.e. over under / back & Lay The prog must also search for and uncover more complex arb opportunities using multiple markets, i.e. for soccer : match odds market, correct score market, asian handicap market Etc both back and lay. The prog should operate on ganes where there are 2 results i.e. Win or Lose and also games where there are 3 results, i.e. Win, Lose, Draw. The prog should automatically or with a click confirm, place all of the required bets in the exchange, and the amount to be placed will be filtered by the lowest liquidity / amount available for any paticular leg of the arb. I am happy to place the payment into escrow but will not finalize payment until the prog has been tested by me. If you have already built an arb prog for betfair etc, I will be happy to test this.
