Creating a plugin for shopify

Hi,

I am looking for a person who will make a plug and add it to the Shopify plugins directory so that other stores can install it as well.

Technology:

php / html / js

Plug Features:

- plugin installation mechanism on Shopify stores (oauth etc)

- next to the add to cart button, adding a new "subscrify" button

- after clicking the button, calling the js function (for now, an alert is enough - ultimately there will be a popup with the option to subscribe to the product)

- adding a subpage with thanks for using the plugin

- regular PHP file with the ability to create an order in this store for the user who used this plugin
