Pulling information from a Database to display on live site.

So, what I am aiming to achieve is the following.

I have set up a repeater with an image, 2 text boxes and 2 buttons in the repeater. These elements are connected to a dataset.

What I want, is for the client to be able to input the information into the database themselves and for this to reflect on the website at a set time.

The time that I want this information to display is a Sunday at 09:00. However, they might upload it at any time during the week.

I have set up a Job Scheduler as you recommended, but I am struggling to work out how to set the database to automatically update when the Job Scheduler works.

I have a basic knowledge of coding, so am struggling a little.
