When I decided to promote my business on Instagram, my friends recommended that I contact SmoService https://smoservice.net/instagram/instagram-media-piar/
where I was offered the best of several PR options. Separately, I want to note that content is the main bearer of the philosophy of your brand, its culture, basic principles, fundamental values, corporate ethics. Letting it go and posting on Instagram anyhow - means reducing the number of loyal subscribers and possible sales from your account. Do not forget about it.
