native Portuguese speaker needed to give advice on machine translator accuracy

There are several free web-based machine translators out there. I'm sure they're all bad, but I was wondering which one works "the best". Here's what I'd like to do. Find a native Portuguese speaker (who also speaks English) and give that person the URL of 4 or 5 of these freebie web translators. Then, you plug a certain English phrase into each of them, and see which one gives you (in your opinion) the most accurate Portuguese translation. I need this for an article I'm writing, so I can't pay much. But I could probably spare a few dollars. Thanks. ## Deliverables advice ## Platform text
