Omg so in - suggestions where to start for BLDC controller in the 48V range?

I’ve been fascinated by brushless dc applications for about 15 years now.
I’ve always wanted to build a 1kw capable outrunner controller and motor. Used to think it was impossible but now I believe it should be a great project.
Anyone in the Seattle area I would love to wonder-twin-powers-unite and build some cool shtuff.

Happy 2019 all.
