I search a part-time job...

To translate,to write documents,to solve homeworks..anything.I already have a job but I need some extra money for my studies and personal issues.

You could try to be a tutor for online courses for money. Create a good and attractive course here:
www.academiaonline.ro (Romanian website)
(or somewhere else, if you find on web):

I give you some ideas for a course accessible to anyone:
-Romanian literatura/history/etc.
-English/French for managers/office/salesmen etc.
-How to write sci-fi/love/children stories.
-How to prepare and win the presidency campaign.
-The guide to idiots on how to brush your teeth.
-Make love not sex (could attract many students).
-How to translate documents.

Anyway, you got the idea.
Good luck.

Thank you very much!!!It's a great and awesome idea!
