Hi,
Your project sounds very interesting and I believe that I'll be able to perform the task perfectly.
As for my experience, you can see for yourself that I've worked here mainly as a content and article writer; but, I've also done some VA work, which included blog posting, forum posting, data processing and entry, etc. Recently I made a video tutorial "How to post backlinks on a website", with script, video editing and voice-over. In my portfolio you can find a sample of video for another website (made in Camtasia). https://www.freelancer.com/u/milanmartinjuk.html
You're welcome to check my reviews and should you have any questions, I'll be happy to answer. I will gladly provide samples of my work if you’re interested.
Kindest regards.
Milan
