website monitoring script

I need a python script to monitor the health of website http://52.53.138.79. Script must download the home page, check for errors, emulate click on search button, check for errors, click the first search result, check for errors, then parse the date which comes after the string "last modified by seller on ", and check that the parsed date is less than 24 hours ago. If any checks fail, the script should write the word "ERROR" and enough information to troubleshoot. If successful, there should be no output.
