Task Automation: Web-Scraping and File Downloading

I'm in need of an automation tool designed using JavaScript. This tool will be utilized to automate a series of tasks on a specific URL. The task is a simple process:

• Visit the URL
• Login using basic username/password authentication
• Input the required details including name and password
• Navigate to the "Orders"
• Out of "Downloaded" or "New", select "New" by checking the box next to it
• Choose to "Download" and specify the format as ".csv"
• "Save as" in select folder
• Logout

This entire cycle needs to be repeated every 30 minutes. The optimal freelancer for this project needs to have a knack for precise, error-free automation and proficiency in JavaScript. A record of successful task automation projects would be highly regarded. The tool's primary function is task automation so I'm expecting efficiency and reliability. Looking forward to your creative solutions.
