Amazon, Google, Social Media, SEO Expert

I am looking for a full time that can help me with:
1) the SEO of my website
2) list products and keep them optimized on Amazon. I have an Amazon Vendor Central account, it's a little different than Seller Central. I sell to Amazon (Amazon buys from me). Experience with Amazon Vendor Central is a big plus.
3) post regularly on various Social Media sites and build subscribers.

Please have minimum bachelors degree and prior experience with above 3 things. You must also be fluent in English (speaking/reading/writing).
