search engine ranking for commercial use

Hello all

Our company is selling websites and CMS. We did
search engine submission too. Now it's about time
to discard that old submission stuff and do real
SEO instead.

I found numerous free ranking reporting services on the net, but I got the
impression that several
of them are not for commercial use. Do you know
a good product/service I could licence?

We are working in Switzerland (not many customers
from abroad).

Regards
Peter
