Can you make money due to speaking different languages?

Yes, there are many websites that hire translators and interpreters, you can work remotely. You can find these websites at http://www.pcworkathome.net/

I speak fluent English and Italian. I have not earnt anything online (yet9 but offline yes I have. I do translations, help shcoolchildren with their English homework (I am in Italy) and work for Italian firms who have English speaking customers abroad. Also I work from home doing phonecalls abroad for anyone who needs to call an English speaking company. For example, there is a firm here that deals with Harley-davidson bikes and I act as a contact here for the firm in USA as the person involved here speaks no English. It all adds up Some years ago I translated the whole of a chat site from English to Italian but I did it for free as I was a user on the site itself and just practicing at the time

I know that there are tons of at-home-jobs for translation. I wish that I could speak another language.

Well there is a freelancer site that has jobs for this. There i have seen some jobs about this. If you know more than one language then you have to translate those on another language.
