Adding Subdomains

[soccio97]

I have a site www.tellmeaboutthat.com which I manage with cPanel. It currently has 9 subdomains which were created and loaded for me by my hosting provider. My hosting provider has discontinued this service and left me hanging.

Needing more content I want to purchased 85 ready made niche sites and add them as subdomains. Since they will be coming from a link provided by the seller, how can I load them under my domain as subdomains?

I not very knowledgable on cPanel but I'm learning so please explain carefully. Thanks.
