Strange request, not that it’s unreasonable, just unusual.
Here, you can post your video and have a number of well qualified people, professionals and amateurs alike, do a very fine job of helping both you and your boy. All of this by the way, with excellent observations and critiques - without cost or in kind, from you.
I want to offer my experience, many years ago, with a similar request.
When I first contributed my experience here, I was contacted via a PM to observe and offer my advice via a download sent to my e-mail address. I didn’t think much of it at time and gladly offered my e-mail address. Within a week, a e-mail was sent to me and it contained an introduction asking for assistance with respect to pitching critiques, referencing this web site. The program that I was using, complimenting my e-mail, screened spam, viruses and other such products. Such was the case in that instance. Instead of a request for assistance, turned out to be a worm that would have nailed my computer big time.
So, I don’t want to dampen your request and those that respond to it - but, considering the nature of today’s computer intrusions, my suggestion to all that respond, tread lightly here.
