Hi there!
Let me introduce myself: name's Nathan, I am a  23 years old French guy, and I graduated last year from translation, literature, media studies and linguistics college.
I am an experienced translator in entertainment, and particularly in videogames, I am waiting for my next contract, and the meantime I would like to offer you my services to translate and localize from English to French, or of English proofreading and help. I can also translate from French to English if you happen to be a French developer wanting to export their game.
It has been proven that a game translated and localized into another language sells/gets downloaded much more as it can reach a new public. I know translation is not the thing you think about at first, but I assure you it is worth it once you give it a go. And the sooner the better, if your game is an alpha/beta/demo, it will be easier to keep translating it as updates come out!
I am mostly working in British English, it is the one I have been taught in school, but I'd be happy to go to American English if you prefer.
I am currently in Australia so our time slots may be different (I will probably be sleeping while you are doing your things during the day), but I can give you an ETA on the translations/proofreadings when I am available.
Please feel free to tell me if you are interested or have any question, I will be happy to answer and get to you as soon as possible. I can also give you examples of games I have worked on, which is not exactly a portfolio as I did not list the games I have been translating for my studies, but it can give you an idea. And finally if you know any other game developer that would be interested, you can give them notice of my offer.
Take care,
Nathan
