Although I haven't graduated with any sort of diploma stating that I can translate from English to French, I have grown in a French environment and attended a French school where I learned English for more than 10 years.

As for experience, the only thing I could show you is the transcript of the TV show Smallville for the episode 4.01 for Devoted To Smallville (which, by the way, they never posted, but I still have the file on my computer). As for whether I'm going to do a good job for you, I guess it's all about you trusting me with what I can do.
