Upgrading teaching slides

I'm looking for someone to update my PowerPoint slides for one of my classes. This will be simple updates, and involves no heavy design or content generation. I will provide examples that I've already done and the rest need to match (updated slide ratio, fonts, colors, links). This does not require expert level PowerPoint abilities, just someone who knows their way around but also has at least a basic understanding of design and space since some content will need to be rearranged on the slide to account for the new dimensions. Most lectures are between 40 and 60 slides and there are 15.
