Good place to get rock for a Cichlid fish tank?

  I am planning on upgrading to a 30 gallon fish tank and wood like some rock (not lava rock) for my cichlid to swim through an stuff. They don't have much of a variety at Petco. Is there a website I can buy some good Cichlid rocks at. Hopefully some rocks that will raise PH too. Thanks.
Limestone will raise the pH.

You should be able to buy some of it at a hardware store .. or if not you can also get some from outside. I usually find them outside and wash them myself. I use a toothbrush to scrub off all the dirt then put them in boiling water for 15 min. This might give you some useful info ... http://freshaquarium.about.com/u/ua/aqua ...

You could also buy some slate tile at your hardware store and break them into pieces to create a cave or whatever you like. I use these in my tanks as well. I just bought 2 slate tiles a couple days ago and broke them to create a cave in my tank .. just be careful the edges can be sharp.
pet smart, pet cetera, mr.pets, petland .. they have good selections .. you could just take a rock you like from outside and clean it well and put it in the tank.
