Hi.
My name is Ruben Farfan Hurtado and I am a Systems Engineer with a Master in Marketing.
I have developed web pages and blogs on various topics (With wordpress). I develop copywriting techniques to attract readers and SEO to position these pages in search engines
I translate also, Documents and blogs english-Spanish and viceversa "manually" to avoid errors as you mention
I also edit videos for youtube and this is one of my passions.
I would love to work on your project, which because of the description is exactly what I do.
Cheers
