Photo editing to remove background from images

I have 45 photos of a girl with a motorcycle that need the backgrounds removed so that it is just a motorcycle and a girl on a completely transparent background. This means removing any background between wheel spokes as well as any other background showing through other parts, cleaning up any reflections on the motorcycles, etc. I have attached one photo for you to view in JPG format as well as the Nikon NEF RAW file. I will provide a DropBox share with the person that I hire to do this that has all 45 Nikon NEF RAW photos that will open in Photoshop. In addition to removing the backgrounds, we need you to do any necessary editing to the bikes and girls to make them look spectacular. To someone who can do great editing work, we will have on going editing work for you. If you want to have a better chance of being hired, feel free to show what you can do on the attached image. The photos are in 4928x3264 and we need them returned as PSD files in that same size. We are looking to get these back as soon as possible!
