In my opinion the best way is start with people from you own country.
WHY?
It is easier to start working if you can explain it on your own language.
The BEST WAY of promoting is FREE classifields ads. Start with your city, After you find few good PSAs , you will get a good TEAM. Then start using other sites, forums and FACEBOOK to promote your job.
I hope my advice can help you.
Wish you all the best.
