I need an attractive powerpoint made from an outline

Description

I have created an outline of a slide show that is already organized by slide, section, and has content to go in each slide. There is approximately 70 slides total. I would like an attractive powerpoint presentation put together from this slide outline using the information I will provide in the course outline document. I would also like my logo to be on each slide as well in the corner.
I don't expect anything too fancy for this many slides, I would just like something that looks appealing and attractive that I can use to narrate for an online course.
