Why don't you just make a topic on this forum about your youtube video? You would at least get a bit more exposure and a couple more people would see your work. What kind of video is it? Is it related to Bitcoin in any way?
The service seems good looking at the reviews, but I would recommend sticking with the lower end products because the price is really high for the higher end products.
There are other people on this forum who offer the same services, maybe you can contact them and ask for some better rates.
