You can start with the GoCentral website builder free for 30 days. When you have a site you are ready to publish, you can purchase/renew, add your domain, and "point" your URL to the site. Within 24 hours your new website will be live.
There are a number of different options for your email. Your best bet is to call our customer support (x.co/247support) to determine what plan best fits your needs, and to get instruction on making the transition as seamless as possible.
