Any weekend online job out there?

Hi, I am looking forward to increase my income and weekends online job sounds like a good option for it, maybe in the future get a full time job with it, however right now I am working with a big company from 8-5, so I am looking forward to work during the weekends, but with something dynamic. I am looking for a job, not a heart-attack.  

I am really good with customer service and I am an outgoing person, good with sales, as my ex-boss use to say: I can sell my mother if I need to. (OMG, not that I would do that LOL).  

I am fluent English, Portuguese, and a intermediate Spanish. I have advanced skills with excel (pivot table, formulas - and basic macros), advanced skills with power point presentations, knowledge of SAP, Share point... summing up: I don't have problems working with computers. Very familiar with social media.  

Please let me know if you know someplace that I could apply, or know job that could use my skills during the weekends, would be amazing to have a job online, btw I am woman, 27 yo.  

Thank you in advance :D
