374132 Google Batch Searcher

I already have a script that will batch search from excel keywords in Google (and in fact return a count on hits). However the problem of course is I get IP blocked by Google when I try to do this, as they are trying to stop anyone (naturally) from using their engine for another site. I simply need to search on 10k or so keywords to get a count on hits and want to be able to do so automatically one time. Does anyone know how to do this in such a way that won't get me banned (e.g. run small packets of 50 every X minutes) so I can just get this search out of the way and done with?
