I don’t think you should buy anything yet, as you’ve been talking about mostly electrical parts so far.
It’ll be way cheaper if you heed the costly mistakes others have made before you.

Just my advice to spend the least money and build the best skate.
And pay close attention to how “deck” and “enclosure” are chosen together, in one step. That’s no accident.
