Please how do I register my domain for free and hosting it. Or is there any site that can register and host a domain for as low as #2,500. Please respond

To register a domain, you have to go to a service (like GoDaddy or netsol) that can register domains. But they all charge a fee for the service.

There are some sites that offer free hsoting, but for minimal pages and for a domain like yourname.wordpress.com.
