Build a Chrome Extension for Amazon

[login to view URL] Here is a good example of what I'd like to have built. This chrome tool allows you to look at products stock/inventory numbers remaining that are listed by different sellers on Amazon. Download it to give it a try. It's free, below are the instructions to try it. [login to view URL] the tool in a google chrome browser 2. Go to Amazon and look up any major product(iPad for example). 3. On the iPad product page, look on the right-hand side of the screen, below the main price for the product, you'll see an "other sellers" section with another price. This part of the page is showing you what other people are selling their iPad for (selling their own iPads on Amazon-like you would on eBay) 4. Click the "How Many?" Chrome Extension button on the Chrome toolbar. You'll see under the price for the product it'll now list how many units are left in stock from the seller. This chrome tool helps competitors figure out how much inventory their competition has left in a quick an easy way in Amazon's resellers' page. What I want out of this project: -I want this extension to have the capabilities that the "How Many?" extension above offers. -This is a google chrome extension tool that people can download from a Shopify platform. I don't know if this is a challenge or not but I wanted to be clear what platform this will be sold from if it is an obstacle. -I want this in two different versions. One version to be free and the other version to be a paid option with premium features. For now, we will keep to a similar model that the link listed is offering. I'll have more details once I've chosen a developer. I've attached two images of what a seller offer price will look like before and after you click the Chrome extension tool.
