Hi. I can definitely help you with the tasks. I am a newbie in freelancing, but I have the skills and training you're looking for.
I am proficient in Microsoft Word & Excel, as well as in Google Sheets. I know Dropbox, but I am not an expert. I am a quick learner, though, and I am very much willing to learn new concepts. I am also skilled with internet researching, and I am quite sure that I would be able to find the articles you're interested in.
I'm good at communicating in English, both written and oral, and following instructions should not be a problem. I can work 5 hours a day, or whatever time you need me to. My goal would be to deliver high quality results in a timely manner, and to meet your high expectations.
Thank you for considering my proposal. If you think I can be of help, please contact me. I'm looking forward to hear from you.
