Need Help Redirecting a domain to an existing template.

Hello, I currently have a Magento Template that is all set up. We are rebranding the store and need the new domain switched out. Looking for someone highly proficient with Magento that can easily go in and make sure the old domain on the existing template is redirected and the new domain is set in place. Also, have a few skin edits that I am unable to figure out how to make happen. This isn't a difficult project, just one that needs to be completed quickly and accurately. Thanks Heath
