Powerpoint Creation for Training Session

I am preparing to deliver a Workshop which is a Training Session on Fundraising Skills.

I am preparing an idea for every slide, including written content and diagrams, but I need someone to create the slides in Powerpoint so that they:

1. Look professional
2. Include infographics
3. Include features like 'fill the box', and highlighting

Please note, I have not finished the preparation yet, but I would like to find the right person for the task so that I can understand (a) cost and (b) format of the brief i.e. can I share a diagram drawn on paper or should I create the slides in a basic way and then share this.
