We need to have a web based solution for PBN hosting, so we can host our site on it.
The solution should take a domain name, then add it to one of the hostin companies (allocate IP, install WordPress etc.)
Then it should provide back information on name servers that should be set for this domain.
I might require a usage of DNS hosting companies too.
So, it can be a combination of cloud providers like AWS, DigitalOcean etc. vps and dedicated providers, like liquid web and usual providers (might require reseller accounts).
I would start from 10 providers as a first phase and then would add more.
