Webscraping Password Protected Site - 24 hour Task

I have a site that I wish to be scraped. This task has been done by another freelancer in the past, and it has broken for some reason, so it needs to be redone. I require clear and detailed instructions on how to use the scrape. The site is password protected (I have my username and Password). This will be disclosed to the winning bidder. I have all the information to start this project immediately, and require it to be fully completed by Saturday morning. There is a bonus for completing this on time There needs to by a 6 month period after the completion of the task for general maintenance and tweaks - this will be paid at an agreed rate of 50% of the price we agree to do the full task. I will only consider freelancers with proven expertise in this field, and with good and consistent feedback. 50% milestone paid upfront, with 50% on providing working sample. I am waiting today to appoint, so please be quick!
