Dave,
I bid on a previous project as well. I can do the whole video for $250 (freelancer charges 10% of that).
The milestone test would be about $55 as the milestone percentage cannot be lower than 20% (freelancer rules, not mine).
I will repeat once again why I can do this for such a cheap price: I am not in the United States and thus $250 is close to my expenses for a month in Guatemala.
I am a native English speaker from Madison, Wisconsin and have extensive experience with Portuguese. I have lived in Brazil, taken advanced courses (I know the grammar much better than native speakers of Portuguese), tutored the language at my university and ran the Portuguese club in addition to having worked on technical projects, literature, manuals, etc.
Please consider me for the job. You will be happy with the results.
Thank you,
Bryce Bray
