Creating and scripting Google slides for an E-Learning course

Description

I need help with the creation of several Google slides and scripting each of these slides to make 2 E-Learning courses that are about 1.30 hrs each.
This is a course aimed at charities and non-profits looking for training on marketing and promotion essentials and another course on the essentials of fundraising. This is a niche topic so experience with Google slides, scripting and charity sector knowledge is key.
Spec with all the sections needed to be built and scripted will be provided as well as slide designs for you to add info in.
A course has already been created so will send this over for reference of how to design and script similarly.
