I need the market cap info for several companies across the last many
years (1999 to current), by month (or by quarter if that's easier). 
Some of these compnaies are on OB exchange, but not all.  Also, I
would like the NASDAQ biotech index and the NASDAQ index for the same
time period.  Please provide in XL format.  If possible, provide
"stock price" and "# of shares".

Please provide source data (or links).
