Hello. I think that I am a good candidate for your project. I am a Spanish citizen, bilingual in English. English was my mother's tongue, and the language of my parents home. You can see how good my English is just by riding those lines.
I have a Law degree from Madrid Universitty, so my Spanish ( Castilian Spanish from Europe ) is simply perfect, elegant and very, very professional.
I am retired, so I can dedicate lots of hours to your project.
Best regards.
