Do this job at the same time as your full time job

I need someone to keep 15-20 tabs open logged in to a website, and every 4-8 hours, they need to ***check*** if the website automatically logged out, and log back in. That's it. The task itself require actual work of 10-15 minutes per day, BUT, it does require you to be available at random times to do it. That is why this job is perfect if you already work online doing other work.
