A plug-in for Shopify and Wordpress ecommerce sites to allow influencers the ability to purchase a product In return for a post/video on their Instagram/YouTube/Social Media profile.

Now that's definitely the hard part. It's possible, but tricky. Another problem would be enforcing they actually post about your product.
