Looking for creative writer with 100% English writing ability

We are an online e-commerce business, and we are looking for a creative and professional writer to assist in rewriting our product descriptions. Furthermore, you will also help with creating new content by writing blog posts, how-to guides, and social media posts to engage users to our brand.

You will need to have the following:
1. extensive writing experience in English
2. ability to do keyword research and integrate keywords into content creation
3. 100% English writing ability with no grammatical or misspelling errors

Ideally, if you have maintained a blog or can provide samples and reference of your writing sample, this would allow for me to best understand your writing ability and writing style.
