Translation of optic in Spanish

I usually charge 15 dollars per hour, but I don't care very much for the hourly system. I can also help with corrections and suggestions, but only if the original text is a serious translation and not an automatic one.
Flying straight from Geneva to New York that does not exist, you must change planes in Zurich. You can also take a 3 hour train ride and then a connection to the airport with a local shuttle.
Many thanks for the corrections. Exactly what I needed to be happy. I want to learn French because it's a great language and because it sound so romantic to me. There is a lot more to improve.
