Welcome to the Q&A Forum

Not me personally, but had a buddy who used Info Cubic for PPC management/SEO and was satisfied with the results.

In most cases you don't need a region based SEO company.  I have multiple foreign based websites we do SEO on and have great success.

Our company specializes in several languages and countries including Chinese, give us a call.  http://www.textlinkbrokers.com/

You can get in touch with Sebastian from http://french-seo.woptimo.com.  I know Sebastian personally and he is really good. He has a strong background with his years in search quality at google and that should count for something. Hope it helps.

Hi, I work for www.indigoextra.com and we offer on-page Spanish SEO and link building, in practice with all the latest Panda / Penguin / Hummingbird updates. All our content is written by fluent Spanish speakers and we focus on content from unique articles, infographics and other high quality links. Best wishes, Martin

try beyondroi for Spanish stuff, not sure about French though.
