Chrome/Firefox Price Comparison Plugin

I am looking for an Chrome / Firefox extension developer who can build a price comparison extension.

The Plug-In has to do the following:

- detect which Amazon product page a user is currently on

- request item details from Amazon’s API (product category, name of product, manufacturer, etc.)

- search an affiliate network API (and thereby use the data of Amazon’s API) for products with a cheaper price

- if a cheaper price is available, the plugin shall display a button next to the price field on Amazon (e.g. “Cheapest price at XXX: XX,XX€”).

- If the user clicks on this button, the user shall be redirected to the online shop of the cheapest retailer using the Affiliate key/token.

A code sample for step 3 (affiliate network) as well as documentation can be provided.

Images as well as design specs will be provided and have to be used to develop the frontend of the extension.

I need this plug-in for both, Chrome and Firefox. Thanks to Firefox WebExtensions, customization for Firefox shouldn’t be too hard. I estimate that an experienced extensions developer wouldn't need more than two days to complete the project.

The ability to also provide a Safari extension would be a plus.

Skills: Apple Safari, Firefox, Google Chrome, PHP
