Thank you. No kits or pre-stuffed boards available ATM, I'm afraid. (If you hear of any, please post it here.)
If this is only about soldering skills, though, don't let that stop you: You don't need any.
(Just in case you haven't seen the video:
If you still feel that this requires too high a skill level, you can alternatively try to build the BASIC Engine Shuttle. It's a bit of a dodgy system (see the project page for details: https://basicengine.org/hardware_shuttle.html), but it does away with the 0.5-mm pitch chips, and it has components on one side of the board only.
What that means in practice is that you can put the board on a stove top, arrange the components for as a long as it takes you, and when they are where they are supposed to be, you simply turn on the heat and leave it there until the board is well-done.
You also only need two orders (board and parts), because it replaces the ESP8266 + VS23S010 with an ESP32 that does both video and computation. The catch is mostly that the hack that accomplishes this doesn't work with every TV. The Shuttle improves on the original in a number of ways, but it has a number of disadvantages as well, so I wouldn't really consider it a successor, but more of an alternative for people with specific requirements.
