No, I doubt launching my website because:
1. They don't give their military projects to me, because their projects are secret.
2. Even if I sell simulation and design courses online (not doing projects), there is very little demand for this field (antenna, RF, microwave) compared to other fields (DSP, network, ...).
3. This little demand itself comes from big companies, not ordinary people. It's a B2B. So I should wait for a long time to do my first sell.
Taken together you've been in this field and I want to know your opinion about launching a website like this.
