Social Media -- 2

I need social media help - I have an instagram page with 25K followers.
I want to set up an online store and I want to link everything together and set up a few different shop fronts all linking back to posts and pintrest.

I want to link my instagram to a like to know it page (LTK), set up a Shopify store, set up an amazon shop, set up a Pinterest page ( I have an old not used one) I want to linking my instagram posts going forward to shoppable links back to an amazon store, LTK page or my Shopify store...

I would also like to have old posts put on Pintrest/ LTK and set up shoppable links in those too.
