Suggestions: invest in someone who already has the experience (freelance FI) to do the very first course and your instructor FI to be an observer in the first course, this freelance FI would also be a consultant providing updated and practical information needed to the school.
Otherwise will be unfair for your student.
Ontrack and Pooleys have nice resources for FI courses (presentations, miniature planes, guidances, etc)
Best of luck!
