What are legit business VPN solutions for 2020 and beyond?

I own a small business and work 100% remotely from various places around the world. My business is growing and I am desperately looking for a VPN solution that is reasonably priced and provides my team with a dedicated public IP address. The goal is to provide this IP address to our customers for whitelisting so that we can access their internal network to support them.

I have signed up for half a dozen services in the last 48 hours and the apps either don't work, they don't offer an actual dedicated IP address that is team wide, or they are extremely slow.

I am tempted to take the weekend and figure out Wireguard for multiple users on a single server but then I have to worry about server security.

Searching online only shows me pages and pages of garbage content all linking back to the same personal VPN providers that we all know are subpar.

I have a team of 10 and the only providers I have found that look half decent require 25+ users and annual billing which I can't afford right now.

Does a service exist that provides a VPN to businesses at a reasonable cost with decent speed and functionality?
