Spanish/German lector with IT(network) knowledge

I need someone to work with my team on a Spanish website on a weekly basis. It's about IT infrastructure ant global networking for middle to big companies... Correcting errors in the automatic translation, correcting sentences that don't make sense, etc. Spanish should be the mother tongue and German should be good in spoken and written. Changes to the Spanish content of the website must be made directly in Wordpress (very easy and simple). Up to 10h per week.
