Here's my honest opinion. I thought of doing the same thing, but when I thought of the time and effort required to finish such a large project, I ditched the plan. While it's a very good idea, without an in-depth and extensive chemistry background (excuse me for the assumption, you might be a genius), your "teaching" will be very limited.

What can you add to the already incredibly comprehensive textbook theory with your knowledge? (You might say your teaching method could be different and helpful, but really the syllabus is quite straightforward) How can you be sure that you're explaining something correctly, and who will be there to verify your content? What can you do that will set you apart from a classroom teacher? If you're sure you can answer all those questions, then by all means go ahead. If not, you may want to think about it a bit more.

You sound like a lovely and generous individual, and I can completely relate to wanting to help out the graduating students in SACE. However, your idea might not be practical and could end up as a waste of your efforts.
