Hi, I ahve very long experience with the betfair API. 5+ years, almost from the opening of Betfair...
I totally do not understand your specs and is this project serious or not :) It is written in a very strange way. If you are interested in explaining me more and working together I am ok to answer any questions. I can do anything that you want with the Betfair API, databases, trading, etc... but need real specs/explanations. If you are interested and are serious feel free to contact me whenever you want.
Best wishes,
Vladimir
