Is it possible I can make my own domain name register. If anybody had any information on how I can do this it would be a great help.
you can be a registrar,
for full information go to www.icann.org
it is expensive and requires a lot of resources
if you are just starting out
you could look into becoming a reseller of a current registrar
this gives you access to a registry at wholesale rates
and if your business grows you can get your own accreditation at a later stage.
what are the wholesale prices you think?
most registrars will wholesale .com domain names for about USD$7-8
do a google search for "domain name reseller"
