I did the search for refractory per your recommendation using Yahoo yellow pages and called the first company on the list and they are a major refractory supplier in my area and after describing what I needed they are able to help me though the gentleman that I spoke to gave a little chuckle when I told him the amount I needed. Probably not used to such a small order but since they were the only ones in the area able to help me I said that I would just buy a case of 20 which he is going to sell to me for $40 and he's even going to give me the cement for free since the stuff they sell comes in 55 gallon drums. Here's their link, very friendly people so far.

Thanks again to everyone that responded to my question. I know for sure that I will have many more questions on bladesmithing.
