I'd like to get a spreadsheet with Search market share for the top 10
search sites (including toolbars and portal searches; ie, google
toolbar would be added to google.com homepage searches).

There would be 3 tabs to this spreadsheet...
1.  Commscore/MediaMetrix
2.  Nielsen Netratings
3.  Hitwise

since each provider gives out different numbers.

Sorry, I need the data for each MONTH for the time period: January
2004 thru April/May 2006.

Market share is measured as "reach", or what percent of the market
uses the (Yahoo for ex) search.

UNITED STATES:  I need the info for the US (not the international numbers)

I think if you look in enough sources on the web, you can get all these numbers.
