Contact Email Gathering from URL

Small budget project. There should be an input file with the name input.txt. It will have a list of urls like [login to view URL] [login to view URL] It may be a list with 5000 urls. The program should find the contact us page. (if the website doesn't have contact us page leave it blank) Then should be able to extract the email from the contact us page. It might be : info@company name mail@company name sales@company name contact@company name If 2 email's available in contact us page, we should collect both. Budge below $50.00 Need to check at my end. Should be delivered with coding. Once completed properly, chance to get regular project. Thanks, David.
