Data crawling IHK Berlin

This is the project. I await your bids. Thanks! Here is the website that needs to be scrapped: [login to view URL] > check the two boxes > enter > In the dropdown select all 'Wirtschaftszweige' (means industry) and all 'Betriebsgrößenklassen' (means company sizes) bigger then '4 - 6 Beschäftigte' data points: I need ALL given info on the website (company name, phone, address, size, industry, etc.) AND ADDITIONALLY email addresses if none is provided on the website (ideally it is the email address of the technical lead or the human resources department of the company - if needed, scrape it from other sources) Attention: The Website only displays 50 search results at a time (despite having much more results). Also, with each search these 50 results differ. That means that two searches with the same filters will show different results making it difficult to scrape. Therefore, the crawling process will probably have to be done a filter at a time (-> by checking only one criteria box a time [company sizes as industry]). Example: Search for all results with company size 4-6 (only) among one industry sector (only). Going this granular, chances are, that there are less then 50 results in total, meaning that we do not loose data. Questions? I await your bids. Thanks!
