Trey, there isn't a lot I can tell from the video (except that everyone working in that salon has a black bubble perm) because it doesn't show enough of the piece itself.
As a promotional video, its exactly like several other companies on Youtube.
The colour match looks good but the end cut wasn't brilliant, but maybe it was exactly what the customer wanted and that is the main thing.

The fact that the place has several good reviews on hair forums is far more important than a video.
Pictures & videos can only tell you so much.
Its customer's experiences that count.
So, based on that, I think you'll be in safe hands.

Remember to ask as many questions as you want and get as much information from them as you can, because that is part of the service you are paying for.

Good luck and keep us posted on the results.
