Hi,
I have developed software for over 20 years, and have lots of experience with most web-related technologies, both server-side and client-side, including HTML, XML, JSON, perl, SQL databases, etc.
Perl is actually my favourite development language, and I write nearly everything with it (including full websites). I have developed in perl for over 13 years...
Over the years, I have also scraped hundreds of websites using many different technologies for various projects.
I understand that you need to adapt 4 existing perl scripts to match changes in the layouts of the sites they are scraping. Depending on the extent of the changes, this might require minor adjustments or more extensive rewrites of the existing scripts.
Can you provide the details of the changes required so I can confirm or adjust the time and cost? I can sign an NDA if needed (you can actually have an NDA signed through freelancer if that's easier).
Let me know if you have any questions.
Note that I am based in London, which should make communication easier, at the very least because we would be in nearly the same timezone.
Jacques.
