Hide the controls based on database setting

I need to show/hide  the controls in asp.net website   based on  some  database  value  setting .
Admin user set the values ON  using an asp webpage and will be turn off automatically after 30 minutes, using "some kind of scheduled job". I need to check this value is on or off every five minutes and need to turn off after 30 minutes.
So when the regular user opens the web page they will see the list controls  based on the feature is off or on at that point of time.
So what are my options to schedule this job to run every five minutes? Can I use SQL server to do this or is there any better option to avoid using production sql server to do the polling every five minutes.
