Web scraping

The project is to scrape a Australian property listings from a number of websites and populate these details such as number of bedrooms, bathrooms everything on the listing into an excel format that can be uploaded in the database. We are not expert web scrapers, so we would need advice on whether we take everything at once or in parts and would be guided by your decision. Most likely we will be banned from the server so you will need to have a back up plan for this
