The standard fee for switching to a different domain is $250. This covers the time it takes us to move the files, set up RSS redirects, etc.
If you need to set up a new domain to forward to your primary domain, you should be able to do that with the help of your domain registrar. If you need our assistance to get this setup for you, the charge will be $25 per domain name. Also, if you need a sub-domain setup to point to a 3rd party website, the charge for that will also be $75 per sub-domain.
