HPI Nitro MT brushless conversion, where do I start?

[ptt81]

I got an old HPI nitro RS4 MT (http://www.hpiracing.com/kits/nitromt/nitromt-m.htm) and im sick of keeping up with intro maintenance and wanted to convert it to brushless electric, where do I start? I've tried searching on google without any helpful infos, there some vids showing its been done but not much discussion about how to actually doing it. I'm opened to all suggestions, links, parts, etc.
