Where do I begin. Please

[MBX5's]

I did a couple searches but not really sure how to go about it. I have a Mugen MBX5 buggy that I'd like to convert into brushless/lipo. I currently run Nitro and theres days I'd like to get away from the mess of it all n just drop and go. I'll maintain my 5T in Nitro but I'm highly considering a brushless/lipo seup.
Can someone point me in the right direction to get started?
Please.
