Is there a service or consultant who could help you get started with the program if you yourself are not so knowledgeable?
Web Scraper can be used to extract data from a large variety of websites; however, a specific sitemap has to be created for each different site. These sitemaps describe to the scraper how to choose from which page elements to extract data, which links to follow to different pages, etc.
You should start by installing the free Web Scraper browser extension for Chrome, and having a look at the video tutorial and documentation sections to learn the basics of how to create sitemaps.
Learning resources are available here:
If you have already created a sitemap using the browser extension, it can be imported to Web Scraper Cloud as well by selecting the "Export Sitemap" option from the extension's sitemap menu and copying the sitemap code into Cloud's Import Sitemap page.
Alternatively, you can search for a pre-made sitemap in the "Community sitemaps" section:
