It's quite simple to add a circuit, but be extremely careful. Always turn off the main power when you work on circui breaker. I'd suggest you get a few books (quite a lot from the public library) and make youself familar with electrical stuff.
If you're not comfortable with that, you might want to find an electrician to do it, but I don't know how much it would cost.
