Sure, or if you want.. i can do it for you.
But please give more details.. what kind of background would you like?
There are about three main types of backgrounds that I would classify as:
1. Pattern Background
2. Gradient Background
and last, but not least
3. Full Background
Would be if I designed an entire photo that stretched across the entire length/width of the site. Although you could make this into a gradient also.. but not going to go there lol.
