Adjust four web scrapers

We are looking for a highly qualified Perl-Professional with extensive experience in web scraping and a proven track record. We have one existing perl "scrapers" for each of the following four different websites (listings platforms) [login to view URL] [login to view URL] (One of which scrapes through the network of proxies.) [login to view URL] [login to view URL] The scrapers run around every 30 mins. Each scraper consists of three perl scripts: 1st script: indexes all listings ids from "list-pages" (a predefined list of URLs with each list having multiple pages) and saves them in a mysql table „listings“. 2nd script: runs through mysql table „listings“ and scrapes data from a direct link based on the ad ids, i.e. [login to view URL]{ads ids} 3rd script: accesses the direct link and submit a contact form on the page. As all websites have experienced minor html code changes, we need to adjust the scrapers in order for them to index the data correctly. We have a unix-server running Ubuntu that can be used for the task. We work with Github and ideally you do too, as it makes collaboration much easier. WE HAVE A DETAILED BRIEFING WHAT NEEDS TO BE CHANGED (INCL. SCREENSHOTS). WE WILL PROVIDE THIS BRIEFING TO QUALIFIED BIDDERS ONLY AS IT CONTAINS CONFIDENTIAL INFORMATION. YOUR JOB IS TO CHECK OUR BRIEFING AND MAKE THE NECESSARY CHANGES TO THE SCRIPTS. AFTER YOU HAVE REVIEWED THE BRIEFING, YOU CAN BID ON THE PROJECT AND WE WILL SELECT A CODER.
