Photoshop Request!

[21nemesis]

I am a professional salsa dancer and was recently in a competition. My dance partner and I took some pix as part of their promotional stuff. Well, I got back some of the pix and was trying to add a backdrop. Since, the backdrop they used was WHITE, I figured it to be a simple process. But, I was wrong. I'm sure for those of you who R Photoshop gurus, it would be a snap. So, I am asking you, could you please help me add my desired back drops?

Thanks,Steve
