Amazon Discount Finder required for Wordpress

I require an Amazon Discount Finder built for my Wordpress website similar to the one found at amazindiscounts com. I can provide other examples. [login to view URL] version required, so this discount finder needs to have German options and all the categories and subcategories of Amazon Germany. I am able to provide translation of everything required from English into German. I will need to be able to insert my Amazon ID account details etc, myself as I will use the script on multiple sites with different amazon tracking IDs (cookie to be set to 90 days.) Must be compatible for use in WordPress (with instructions for installation on other sites and how to amend for amazon account details). I am looking to have the Amazon Discount Finder look similar to the one on the web site stated above or in another sample page that I can provide once the project has been awarded (sizing will be roughly 2/3 of the page which is the main text area). Necessity for picture graphics can be discussed once the project has been awarded. The same goes for a requirement of a logo. The 'other options' shown on the example site would not be required. Needs to work when viewed on mobile devices (I have chosen a fully responsive Wordpress theme). Simple and robust. Needs to work reliably.
