Betfair / Bookmaker Bets

Prior to moving on to the software creation, I require bids for the following solution with regard to trading on Betfair and also using bookmakers accounts. First of all, I wish to place a back bet on a correct Half Time / Full Time bet with a bookmaker,? i.e. 100 Euro bet on Fav at Half time / Outsider at full time, at odds of say 30.0. Should this prove to not be possible, then? a 100 Euro bet on the Outsider at Half Time and the Outsider At Full Time, which should be at odds of about? 8.0.? Or should both the above prove to not be possible, then placing a back bet on 0-0 with the bookmaker at around 14.0 and again, using related markets in betfair to create a break even or profitable outcome. I fully expect this bet to lose and am happy for it to lose 99% of the time, so dont worry about this bet losing. What I am now looking for, is a way, using any of the related Betfair markets, i.e. Correct Scote, Over/Under,? Match Odds, Next Goal, Etc. Etc. Etc To ensure that I either profit or break even? if this bet with the bookie does not win. I have looked at laying the Fav for half time and laying the outsider for full time, but the odds do not allow? a profitable outcome.? I have looked at just laying the outsider, but, again, I am exposed to risk, as if the outsider is winning at half time, the bookie bet is lost and I would not be able to trade out of the Betfair lay bet on the outsider to cover the bet I lost with the bookie. If someone can come up with a solution here, with either bets that can be placed at the same time, or bets that have? to be placed as the match is in play. Once this project is completed, I will then I will also need some software to be coded to search the various markets for suitable bets, then once this is completed, some auto trading software. I would also be interested if anyone has a system that can do the above, i.e. a high odds bookie bet and bets at betfair to ensure that when the bookie bet loses I still make a profit, using any other markets. Please only bid if you have worked out a 100% way for this to be done.
