Crawl public website and collect organisations details

This is a web scraping project. We are looking to collect the information from an online public register and scrape some of the the information into a spreadsheet. It is public website which does not require registration. The scrape will need to be limited by an onsite search parameters to get around the maximum number of records that can be shown at one time and might require more than one run through using different parameters. The details to be scraped are stored on unique pages for each record. The search results are paginated with back and next buttons. In total there will be around 3000 records. We would like the final results output in standard CSV or XLS document.
