As a spanish speaking native who studied his whole life in an american school I am as fluent as it gets in both languages. My scores on the translations tests prove I am capable of doing this job. You can check my profile so you can check my experience. I have seven years of experience working for a mining company in which one requirement from my job was to translate all the documents for deals with american partners, that included emails, contracts, messages, etc. I am the hardest worker there is that's why I can guarantee your complete satisfaction with my work and because I know my capacity I can assure you I can work even on a one day due date
