Manage and grow social media accounts -- 2

I just set up a new business and needed help to grow my social media accounts organically (Facebook and Instagram). Other than generating high-quality posts, regular posting and managing these accounts (responding to comments, etc.), you will need to research the correct hashtags for the posts as the priority is to grow the accounts. If you are posting about my products on Facebook, you will need to tag the relevant products. I am also looking for influencers to send the products to and would need your help to find the right influencers. You will need to demonstrate that you have successfully grown social media accounts in order to be successful for the role. Suggest any successful strategies you have adopted in the past would be highly valuable. I am looking for a long-term collaborator to work on my accounts.
