Betfair API Trading App / Program Any code welcome + past projects

Overview I need an application to be made that can connect to Betfair's API service to retrieve information and submit bets. The free service is ok but if someone is able to offer me access to the commercial version then that would be ideal. Previous experience of betfair API is essential. I would like to install this on a Mac if possible with also the option to build it as a Iphone app. However if it is only possible to have it built for a windows machine that is no problems I will run it in a virtual machine on the mac. I will leave it to the coders to choose the best code to us and more than interested in coders who have similar software that could be adapted as the functions are common trading functions. I have previously used a frontend which outputs the data to excel auto updating enabling me to view the data and run calculations from the data and submit bets through the excel sheet, this would be a good solution but I am open to suggestions as this may not be the best. I will be using the program to trade on betfair markets and also collect data. I can send over an excel sheet displaying how I would like to view the data and programs functions on request by programmer. What I need the software to do Load up a betfair market Continuously retrieve data at every second which is the limit for free API : Needs to display prices as on Betfair in a ladder format for the 3 favourites. See attached file to see the layout. Needs to be able to enter the amount to back and lay One click submission of bets by clicking the price on the ladder and if clicked again cancels the bet immediately. Green up function. This lays a selection at a calculated amount to spread the profit across all competitor s in the market. Someone with experience with betfair API will know this function. I would like the option to auto green up as well. Monitor the book % and make automatic bets dependant on the book % and a couple of user settings. Would like programmer to be able to use skype for updates on project etc Please contact me for more information and for excel spreadsheet to give you a real idea of what i need. Andy
