Instagram business specialist

We are looking for an Instagram business specialist who can help us with problems with catalogue data. Some products which are not anymore on our Woocommerce webshop are still shown on Instagram, and product variants with the same image are shown. At the same time, we only want to show the parent product instead of the different variants. Next to this, there are some errors shown which need to be solved.
We use a WordPress plugin and Facebook pixel to fill up the catalogue.
