I have worked advertising for the facebook page called "The Flash Universe" for 4 months, 20 hours a week.
I have managed multiple facebook pages, with varied content, for example: Video games, Business, News, Music, among others.
I can work up to 40 hours a week, no more, because I also study.
All I need is $8 a week to pay for my tuition. (yes, studying is that cheap in Venezuela)
