Transform Slippers to Socks in Photo

I want a graphic designer to tweak a family picture for me. Specifically, I'd like the slippers in the picture replaced with socks. The socks desired are of a plain black design, no patterns or colors, just solid black. This job requires someone with photo editing skills - particularly with Adobe Photoshop. Experience with fashion apparel editing in photographs will be a huge plus. You need to make the socks realistic and seamlessly integrate with the rest of the image. Keywords to note for this job: Photo editing, Graphic Design, Adobe Photoshop, Realistic Rendering.
