Convert Old PowerPoints

I am looking for someone to help me convert some old PowerPoint presentations that I have in need of an upgrade. While I don't necessarily need the content of the presentations updated right now, this may be something that I will need help with in the future. The output format I am looking for is PowerPoint, and I don't need the original fonts and colors retained. This project requires someone with knowledge of PowerPoint and the various features and functions available. Ideally, they would be able to take these older presentations and place the content into the newly designs template we already have. We have about 18 powerpoints that just need to be transferred to the new template. I would need you to make the click thrus and transitions are professionally done. You do not need to redesign, add images or text. Just take the content from the old powerpoint and put it in the new powerpoint. Make sure it works and looks good.
