Hey.
I am taking an Engineer's degree on computer science, currently in 3rd year. I am looking for a part time job like the one you're proposing. I can write the captions for all of your clients videos and I'm available to work until you say otherwise. I am Portuguese but I am fluent in English, as half of my family is living in England at the moment.
Would love to talk to you and discuss further details. I am hardworking and very thorough, so captions will only be delivered when I feel they're flawless. Proposed rate is 2-3$ per video minute.
hoping to work with you.
regards,
Ed
