Chrome Plugin

I want to create a Chrome Extension/plugin when users can download. Once download they can login to their account with us. (account info is in [login to view URL] so need to integrate with) Once logged in, the plugin will retrieve the user custom address from the system and store it. Note user will get different address in about 10 countries. The user can then go to websites such as [login to view URL] and in a click of a button from the plugin (or automatically) his custom "USA" address will be pasted rightly in the address fields in [login to view URL] or any website checkout page. User can also select any other country and have that country address copied. Should work also with major websites such as WordPress/woocommerce, shopify, Walmart, Target, Sephora USA ... This is my first post on this, so let me know if any additional info is needed at this point. Added 2 screenshots showing the countries list, and then a samples of one address, the USA. Else if you read this, please post the word "Plugin" to know you have read this and put your price and duration. Thanks.
