Hey,
Skinning takes some effort to
learn, so if you don't want to learn you're going to have to look at alternatives, as it's unlikely a skinner has time for personal requests.
Maybe you would prefer a simple Background Changer, which sets the background to any picture you want. See
here.
However, using a small image like yours, even if you were making a skin, is difficult as it will stretch and won't look very good.
