Modify Powerpoint into company branded slides

I am looking for a freelancer with experience in modifying Powerpoint presentations to match my company's branding guidelines. The purpose of the presentation is educational/instructional, and there are more than 20 slides that need to be modified. I have a specific brand guideline that needs to be followed, which includes removing copyrighted branding and replacing it with the American Massage School branding. The ideal freelancer will have experience in Powerpoint design and branding, and will be able to deliver a professional and polished final product.

1.Remove references to chapters in the slides
2.Change All pictures and charts into matching picture types and chart types. May have to alter charts and develop new pictures.
3.Replace Pearson with American Massage School

Included is one Slide that will need altering into my brand.

If this project goes well I have 100 more of these to alter
