Web program which changes password

The scraper will be installed on Linux server and the scraper will have a webpage that is associated with it. The program will change my password for some website. (So the program is some sort of web scraper) If I click "Tell me password" on the web page, it will tell me my password. When some time (say 5 minutes) pass, it will automatically re-changes my password. It will log when I clicked "Click here" and log when the program changed password. The password should not be accessible by any other way than clicking "Tell me password". Tell me how many hours you can work per day. If you don't write this, your bid will be immediately removed. Also, tell me your detailed plan on how to meet my goal.
