macOS on Razer blade stealth?

I have no experience with hackintosh and would love some help. I'm looking to have Linux, windows and macOS all on one machine and I have no idea how to get macOS onto mine.

My computer has an i7-8550u with 16gb of ram and a killer WiFi chip ( Killer™ Wireless-AC (802.11a/b/g/n/ac + Bluetooth® 4.1)) I'm going to replace the card because I hear there are no drives for the chip supported on Linux. I also plan on getting a 2tb drive and allocate about 500gb to macOS and Linux the 1tb to windows. How do I go about installing it on my computer and getting it.

I would like to get help with

- installing macOS onto my computer and getting it usable

- be able to boot into windows or linux

- possibly be able to do this without having to reset my windows

Some questions I have are

- is this legal lol

- how well does macOS run

- how much time does this usually take

Thanks for the help and if you need more info or clarification just ask :)
