I have done this many times. I am based in Guadalajara, Mexico and I represent an American financial services company so every time there is a meeting with the Mexican clients I function as an interpreter.
If there is any business jargon, I can translate it fast and effortlessly.
A 5 minute Skype call would be enough for you to see how proficient I am in both languages and, if this is a recurrent thing, I would be willing to do the first meeting free of charge.
