Composite Bedroom Setting into a Background

I need a highly skilled photoshop professional who can composite the studio shot of a bedroom setting that needs to be placed into a chosen background image. The photo has been taken with the proper perspective and lighting. That being said - we need a highly skilled person to make it realistic. You would need to include realistic shadows, reflections, transform where needed, dodge and burn etc, etc The files including a very cheesy mockup of what I kind of need can be downloaded from my Google Drive here: [login to view URL]
