Hi
It doesn't have to be professional, just make it real, be genuine & honest, have a go and make a desicion afterwards, or get someone who is doing photostudies as a course to do it for you.
My wife has a dance vid on youtube, it has had 15,000 + views, I did it on my little digital camera and it took less than 2 mins to shoot, no editing and uploaded within a day, good promo for her classes, she's very busy!
Kind regards
Martin
