Social Media Account Handling

I am looking to obtain help with my social media account and am particularly focusing on Instagram. My primary goal is to drive sales or leads, although I am open to suggestions regarding the target audience. I need assistance managing the account, such as creating engaging posts, interacting with followers, responding to comments, and strategizing how to accomplish these goals. While I do not have a specific target audience in mind, I am open to suggestions to reach the people most likely to be receptive.
