I'm native when it comes to Spanish and fluent when it comes to English, I've previous experience when it comes to translate books and documents, and, I'm working full time as a freelancer, so expect your project to be delivery quickly and with quality.
Now, when it comes to this project, I do have an extensive experience with words and documents, now when it comes to forums, I have been a moderator in the past for gaming forums in Spanish, so commenting, identifying and also creating videos in Spanish is not a problem (Something really important that I want to highlight, is that my voice is one of an announcer, is quite deep and I know how to articulate properly, so explaining a software wouldn't be a big of a deal), because I have worked in the past with networking., I look forward for your reply.
