If you go with the peg board may want to look for any retail business auctions in your area.
Here is a post that I did about the wal-mart auctions in my area.

Also some of the walls included the 4 ft and 8 ft mounted under the shelves. Have also seen full cases of bulbs sold out of some of the maintenance sections real cheap. I got 2 or 3 boxes of the 8ft clear tube protectors out of the last maintenance room I bought for $10. Only added one pic back but if you want the others let me know.
Here's another site you may also want to check for peg board.
