Collect daily car ad data from the following web pages: [login to view URL] [login to view URL] and store the initial data and any change (for instance price change, km change) on a Postgre database. The script should be developed with Python and should not be blocked by the website due to too frequent queries. The information for each car should be stored in a tabular form on Postgre. When the ad is not available anymore, it should be stored with a closing entry as well. The main goal of this project is to track how long a car ad is posted and how frequently the price and mileage changes until the car is sold.

Hi, I am interested in your project related to build a scraper to pull ads data from [login to view URL] and autoscout24.ch. I checked both websites, autoscout24 has at the moment 147 240 ads and [login to view URL] has 9960 ads. I will build the scraper in Python using multi-threading and with proxies rotation so it will be very fast and never get blocked. The scraper will be schduled to be run on a daily basis and the data will be put to PostgreSQL. Please send me a message so that we can discuss all the details. Thanks, Ramzi

I checked both sites and I can provide you fast and effective Python (Scrapy) spiders that will check all ads and save information into PostgreSQL database just like you want. My script will check any mileage or price change and update database record. Also if will change Ad status to closed if original ad is no longer active. I have worked on similar projects many times before (see my reviews) that's why I'm sure you'll be impressed with my work.
