Hello,
My name is Benjamin, I'm a native German but I currently live in Central America. I use three languages on a daily basis (English, Spanish, and German).
Also on a daily basis I'm doing translations back and forth among these three languages. Marketing material, presentations, websites, etc.
So I definitely think that I can help you out.
Although I'm not sure if 20$ fixed price is for the whole project of 12-15 hours.
I usually charge 15 usd/hr for my work.
If you're looking to pay 20$ for 12 hours of work, then please disregard this proposal.
Please feel free to contact me for any further details.
Best regards,
Benjamin
