Converting to Bing Maps

I have a small project with using Google maps that I would like converted to using Bing maps. There are only 7 or so functions that need to be converted, only 4 of those are larger than 10 lines. essentially a user just drops pins, searches, and updates a map. Unfortunately I don't know Bing maps well enough to get this done in time. The estimated time on the project for someone familiar with these maps is about 3 hours. I would need this done asap as well. Ask me if you have questions, I would like this started today and gotten back to me soon after.
