Keyword Ranking Site Comparison Tool

I have a client who wants me to show where his site ranks on Google in comparison to what he sees as his top 5 competitors for 50 or so keywords.
Now I could do the whole thing manually, i.e.do a search for each keyword and then go through the results and see where the sites are ranking.

But frankly who's got time to do all that? Anyone got a recommendation for a tool where I can insert the domain urls and the keywords to check against so I can click a button and see the results?

I did try googling for this but had no luck.

Will reward the person with the answer with a direct link to some IM eBook and course video goodies for free.
