How can I find contacts for companies represented by subdomain stores?

Hello everyone! I am trying to find the best way to pull in subdomain links and automate enriching them. The subdomains for logoshop.com and promoshop.com have clients that are using them for subdomain stores like https://sofn.logoshop.com/ and there is contact information on each one of these sites. HOWEVER... I would like to take it a step further. The contact on that site is who handles that company but I would love to know if anyone has a suggestion on getting that data and then also pulling into a new work flow the company being represented like the Sons of Norway(https://sofn.logoshop.com/) and finding their contacts.
