We follow a similar structure at my home. They have iPads but strict screen time limits during the week, and less strict on weekends if we are home. No social media, no chat of any kind, and they are not able to install apps without me approving them (iOS parental controls feature).
YouTube is an interesting one. Like the Internet itself, there is some really great stuff, but letting them roam is a recipe for disaster. YouTube Kids has gotten better over the years but nothing's perfect. On one hand, I didn't want to block YT completely but I also wanted to be able to approve anything they watch. So, I did what any other programmer dad would do in this situation and built what I wanted.
They now have a permission layer on top of Safari (as an extension that cannot be disabled when coupled with Safari's content moderation setting). I set Safari to only allow YouTube and any channel they try and view that I have not approved will require them to send a permission request to my phone. That "permission request" is a button + them coming to me with "Hey Dad, I sent you a request". It's worked quite well in our home and has opened a nice dialog about what they are trying to watch and why. I made it public if any other parents are interested -- https://www.sunscreenapp.com/
I would try and add a bigger twist to standard x vs y poll to separate yourself. The basic concept has been done many times before, without massive success.
USvsTHEM (http://usvsthem.com) is a site that I co-created - and still very early alpha; but adds a twist that centers a debate around people and their network of support. There is no browse-able stream yet, as the alpha release was meant to test the social utility.
I've used escrow.com with great success. You can split the fee to escrow between the two parties or have 1 side agree to pay it. I think the seller decides what the split is, so make sure you agree on it before they set it up.
At first i was cautious since escrow.com looks like it straight out of 1996 but it's legit.
