Dev Guy can help your business with Domain Name Registration of one or more domain(s) and configuring the domains in DNS.
It is important to get the domain name right and potentially purchase more than one with different extensions, to stop competitors from purchasing them. It depends from business to business and the market that your business is operating in.
Dev Guy can also help you transfer domains from different Registrars into one Registrar if you need too.
If you would like to discuss your requirements or require any further information, then please don't hesitate to contact Dev Guy. Skype or Google Hangout sessions can be arranged to demo software.
