Add productguide on Wordpress website

On a Wordpress website i need a productguide to be added. It contains of information about products and companies (related to each other by companyid). The productguide should contain a searchbox (with autocomplete function) and search in the productlist. The result should show the products which match the query and this line of information should linke to the webpage of the companie. Editor should be able to add/change information about products and companies in the backend of Wordpress. I have added a sample of company and productinformation (there are about 1500 products and 20 companies). I have also added a screenshot of the webpage and the position of the searchbox and searchresults. The website is not public at this moment, you can reach it by changing the host file on your computer. You will get the IP address and login information after accepting the job.
