At this time it is hard to calculate a market cap. Audited financials would help out a lot and I expect some sort of financials filings in the future.
However lets take a hypothical number and try to build a market cap around. Say for 2008, Remodel Auction completed 200 projects @ an average cost of $10,000... that would equal $2mil in Revenues 2008.
What would you say their market cap should be?
Now if they could expand outside of the NC market in to 10 more states, that would also increase the revenues.
