Hello! I am a professional programmer with over 7 years of experience using Python. I have read your project description, and I can create the Dead Link Scraping/Crawling program you require. To do so, I will use the libraries Mechanize (for web automation tools), BeautifulSoup (for parsing html), and Selenium (for working with AJAX or Javascript, if necessary). I have written many web scraping programs in the past, and I would be happy to show examples. Please contact me so we may speak further and so I can send files. Thank you for your consideration.
