SEO & proofreading in French

Hi there,

I have a client who has a French version of their site and needs the following:

1. Check keywords are OK and perform additional keyword research where required - I can give tips on this, but you will need some SEO knowledge.
2. Ensure each page has the correct keyword placement and density (I will provide details of what I want for this, so it's very easy, but I don't speak French so I can't do it!)
3. Ensure all meta descriptions are written correctly - make sure each Meta Title and Description is written correctly and is appealing for a French audience.
4. Proofread each page to ensure no spelling/grammatical errors

There are roughly 70 pages, and I will need you to sign a NDA before logging in to the CMS - how much would you charge?
