What you plan to do is not destructing and if this is what you plan to do, you need to know whether is there really a market can afford to pay you money to attend the class?

I strongly suspect your challenges are:
1. whether it really available market that can pay
2. lack of publicity and public education of such needs
3. insufficient brand name/ reputation to give confidence to the students and local educators to support

There are many alternate approaches available:
1. Check this out https://byjus.com/ (but you need very rich investors)
2. post your training into a web platform with the good market place (e.g. www.udemy.com).
3. look for a good mentor who is very experienced in startup business like yours
4. don't start marketing unnecessary when you cannot answer the 3 challenges above ...

The above are my comments based on my over 20 years of experiences as an entrepreneur and management consultant- hope it is of some help.
