@Alex Silang I am not claiming to be an expert but I think your best bet would be to look for a turnkey provider in a place conveniently close to you and see if they would be willing to give you a role in what they do - maybe doing something you are already good at, so they benefit, and in return you see and learn what they do.I am suggesting this because in my line of work there are many many people with academic and theoretical knowledge but they often haven't ever really applied any of it.
