Adding a Specific Dollar Counter to my video?

Heya!

So I have put together a video of a recent large vintage video game pickup.  The main focus of the video is talking about the value of the games I purchased to see if I got a good deal or not. 

Ideally, I would love to put a running dollar amount in the corner of the video that shows the value of each game and adds to an overall total.  For example, if a game was worth $200, the counter would go up by that amount.  Since the video will show roughly 1,500 games I don't see an easy or automated way to accomplish that.  I am wondering if there is an easier way to get a similar effect.  I know the overall value of the lot I bought and was thinking I could just have a running dollar counter that starts in the beginning of the video and eventually hits the overall number at the end.  I could time it so it hits the final number as the video ends.

Is there an easy way to do this?  Does anyone know of an overlay that was already created that I could edit?  I just bought Premiere Elements 15 and am fairly new at editing.

Thanks for your help!
