help me sell on amazon

I have created my own product (teeth whitening kit) and i need help with having the product on amazon FBA. The account has been created and was approved, but not knowing what is the next step. I also do not have any professional pictures for the product itself to be presented on Amazon, which is something very important.

I am also looking for someone who can help me with marketing material, such as writing about the product and putting in into a presentation. It is a marketing/Sales job. more info is to be diffused.
