I am in Colombia. I am looking for a job or business which wouldn´t take many hours from my regular job?

I know that many people who work just 2-3 hours a day get a great earning monthly just by doing things from their own homes or pc´s, without affecting their day-to-day lives. Where can I get a job or business like that taking into account that I am a colombian resident. I wouldn´t like to spend the rest of my life waiting until I am old enough to retire and working for the same company 8-10 hours every single day. A friend and I share the same thoughts and we are looking for a job or business which can give us a big salary in no time so we can take a Latin bride.
