Chrome extension that displays seller info on product page - 30/04/2018 19:30 EDT

I am looking to develop a chrome extension. The extension must do the following: Visitor enters online marketplace ([login to view URL], sort of Ebay of South America). Visitor clicks on product but Chrome extension ads a small area on product page with additional info about seller (Seller's website, phone number, adress). This info will be recolected by our company and stored in some sort of database that is compatible with the chrome extension. Workflow would be as follows: - Each seller on marketplace has a unique seller name which is given by mercadolibre, so has nothing to do with us. This seller name is displayed on each product page of products that belong to that seller - We add seller info to a database. So each unique seller name has a phone number, address and website associated to it. - Marketplace visitor clicks on product, chrome extension retrieves the product seller's unique name and searches the database for the seller's data. - Chrome extension displays sellers retrieved info on the product page - Visitor can now see seller's phone number, website and address and contact him directly.
