1.) Create websites. Monetize them with adsense or amazon. Passive income.
2.) join freelancer sites upwork/odesk, fiverr, etc. Offer your expertise. $x/hr sa upwork. Do minor tasks sa fiverr. 1 gig/task = $5 (less $1 fiverr fee; $4 = net)
3.) develop android/ios apps
4.) develop wordpress plugins/themes
5.) develop browser plugins
6.) identify mo needs ng tao. Tapos offer mo solution for their needs (ie. sell eload products. Kahit sa office dami nagpapaload)
How about assemble a desktop PC then sell for profit?
BTW, if you'll be working as freelancer online, please do not make your price too low just to get the job. Freelancers who work for $1 an hour is hurting fellow Pinoy freelancers.
