Hello, We want to scrape a classified ad website for some information. Estimated number of links to be scrapped: 2 Million. It's not an easy task that's why we are looking for an expert in web scraping. In addition to the normal methods which websites use to detect and prevent scraping, you may face: -> Javascript & checking if cookies are enabled validation code. -> Captcha (see the attachment for captcha example). I want to know your suggestions or ideas on how to pass these problems, only bid if you are sure that you can handle these problems, because if you can't, you won't be able to scrape except for few links before you get detected. I'll provide the link of website and what we need to scrape and further information in private chat. I want an error free, clean and well documented code. I want the code to be in php or python, however, if you are able to deliver it perfectly in any other language I'm open to suggestion. Milestones: 50% After getting the code working, and delivering sample of 50,000 scrapped links. 50% After getting the code and testing it on my side. Please bid only if you are sure that you will be able to do it. Thank you

HI, I have developed scripts for similar sites. We can solve the captcha issue with DBC(deathbycatcha api) which is 1.5 $ per 1000 captcha solves. Regarding the other we can use HMA to keep changing proxy every 5 mins to keep it running. Kindly send me the site link i might have crawled it before. Thank you

I specialize in web scraping jobs like this one. You can see on my profile that I have completed many similar jobs. Don't make the mistake of hiring an amateur, who doesn't have the skill set to properly complete this task and will only waste your time. Hire me, a professional with a rock solid reputation and over 8 years of experience specifically in writing scraping code like this. I know what I can and cannot do, and I won't waste your time by saying I can do something that I can't. because I exclusively write scraping code I know what to expect and I will always live up to what I tell you, and will also deliver a higher quality final product than my competitors. This can be done in about a week

Hello! This project is wild and exiting! I can code php fluent, and i feel capable of coding something to do the job, after i observe how the anti scraping of the website works, and put up a plan I think that I can make it, can make you a php script to run in your local machine with the php interpreter, and if using windows can make the script much faster, kind of multi-thread. Edited: My plan is to inspect the headers, understand how the anti scrap works with php session, cookie, or ip, understand all that stuff, test if it works requesting the same page or different pages, to get a better knowledge of the anti scraping, make sone tests, and in last solution ill perhaps suggest a script that use free public proxy lists to get X number of pages, the script can get all the proxys by itself and do it magic, and output everything it is doing, i hope to understand and bypass the anti scraping. I hope to read you soon

I have three years of experience in web scraping using python frameworks like scrapy, beautiful soup or selenium. I also made simple captcha solvers in python image library. Please provide me some sample links so I can see if I'll able to deal with it. Cheers, Mikolaj
