Heart Rate Monitor/GPS/Chrono Device Agent

Looking for linux programmer to develop a desktop program to transfer data from a Polar, Garmin, training device that records heart rate, route via GPS, time, pace, etc. I have access to original API. Example: I have a Garmin 310XT. It records, my HR, pace, route, distance. I plug the device into my computer and use a device agent to transfer that data to a website where I can analyse the data.
