Hello there!
I am a Video Editor for around 8 years which I mostly done videos for myself. I know what you are looking for and I clearly understand all the requirements that you need. The thing is that I haven't had a project/job to do a promo for someone, but I know how it works. So instead of sending you one of my promo videos (which I don't have one), I can send to you a sample of your current promo, just to make it clear to you of what I can do. Message me and check out my skills with the sample I give to you.
I promise that it won't be a waste of time for you! Don't hesitate for that! Have a good day/night.
