Shelves are one thing I won't pay someone else to do... Unless I want it to be super pretty, then I would have Christine at Twilight do them. I learned pretty quick how to use a saw and make my own. By the time you get done buying shelves, you could buy an inexpensive saw and a few $7 6 foot long pieces of kd pine. Then all you need is some hardware and some elmers wood glue to attach poo guards.
