We are looking for someone who has experience writing scrapers. We have done this before so we know the general way to do it. We are not seeking someone who "thinks" they know how to do it. We only want someone who has written scrapers before specific to the www.jigsaw.com site.
You should understand how to use proxy servers. We will provide you with up to 500 proxy ip addresses. Please send us samples of your work as well as proof that you know how to do this job.
