Customised Betfair Automated Bot

I’m looking for an experienced and skilled betfair programmer who can transfer my strategy into a 100% automated betfair bot using excel spreadsheets. A simple front end screen would be beneficial. I currently have an excel sheet I have built to calculate my own staking plan. I need to be able to monitor markets to place three bets when criteria are satisfied. Once result is known the result needs to be recorded so calculation of next stake can be done. Safety mechanisms need to be built in. eg. only starts to look for next bet when result of last comes in. This may lose a few bets but would stop bot miscalculating. A simple front end screen would be beneficial. The bot must be able to run on windows pc (essential) and macs (optional depending on price). Must also use Betfair API. A detailed description how the bot should work will be sent afterwards. Hope to hear from you soon. Kind Regards BenNevis
