The big box stores have lots of nice shelf sets. Another option is to just buy some attractive mounting brackets and some lumber, then finishing and painting the wood exactly the way you want. I don't have much of a woodshop, so I have posted offers from time to time on Craigslist to trade a plate of homemade cookies for some nice router work on a shelf or something like that.
i'am sorry but..avoid the big box stores!! go to your local lumberyards! you will get better service and quality!
