2018 IPVanish and Gargoyle 1.9.1

[Statik]

Greetings all,
I'm a longtime Gargoyle user but I've never looked into setting up a VPN. With the way Net neutrality is under attack lately, I'm looking at setting up a VPN within Gargoyle. IPVanish looks like a good price/performance, they are recommended in more than one place, and they have instructions for setting their VPN up on my router (TP-Link Archer C7), but with DD-WRT.
I've looked through the documentation and the forums and all of the articles are both old and seem to be more hints than instructions. So I have two questions:
1. Before I signup for their service, has anyone successfully setup IPVanish or something similar in Gargoyle 1.9.1?
2. Can anyone link or produce a detailed tutorial on how to set this up?

Thanks in advance:
Statik

VPN providers are not supported

Eric made a decision that most of there uses are not legal. Or something to that effect.

I think some support could be provided, but it is what it is.

While I understand that there may be nefarious uses for VPNs, there is a push on for people to move to VPNs to protect their information and identities from phishing and skimming attacks. This is my interest.
If anyone can offer a tutorial, I would be much obliged.

Someone did it with PIA

Any tutorial applicable to Openwrt will be largely applicable to Gargoyle as well
