Instagram influencer fitness

I am looking for a social media specialist who can help me increase my Instagram followers and engagement. I have a specific theme and content that I want to post on Instagram 3-5 times a week. I am interested in working with somebody who will be able to create content that aligns with my brand message and can craft posts that engage with my current and potential followers. This person should also be knowledgeable in the use of hashtags and paid influencer sponsorships. It is important to me that I am able to reach the right people on Instagram quickly and effectively.
