Data Scraping - Exhibitors list from public events websites

I need to scrape data from a list of specific events and websites to collect exhibitor names and contact information. The data should be provided in CSV format. Ideal skills for this project would include web scraping and data mining, as well as experience with tools like Python, BeautifulSoup, and Scrapy. Some of the website use iFrame. Attention to detail and accuracy are also important. Please provide a proposal outlining your approach to this project and your relevant experience.
