I think (and thats only my own opinion) t 19 years of age is too young to be doing such an activity as a full time job, but its not too early to start. That being said, the most known motivation speakers in Jeddah are; Rashad Fakiha, Dr.Walid Fitaihi and Ahmad Al-Shoquiry + the many other Business to Business motivation Speakers coming from Dubai.
My Advice is to start as an assistant in an HR training/development centers like Tamauzy, Meirc and Strategy and Teams(last two in Dubai) and then develop your career from there.
If this will help; Rashad Fakeeh Center in Jeddah is in front of Aziz Mall (the building where Bank Bilad is located), Dr. Walid works in IMC and Shoquiry has a café called Al Andalusia in Khaldiah prince sultan Street.
One inspiring guy is Ammar Bogis, he is the Nicholas Vujicic for Arabs
