Need an Expert content writer for creating my business profile

We are a Global Diamond exporters. We are creating social media campaign to promote our business. Hence we need a highly expert content writer who could write professional content for our company that could present our company's vision, product offerings and services to the public and attract massive buyers to our social media accounts and website.
The content should include company's strong history, vision, products we offer and exceptional services we offer.
This would be a long term project freelancer once hired would be given further more work and paying opportunities as well.
Thank you
