Create redirects

I need to create Redirects from the old name's DNS Provider to new domain main name DNS. This is the story we are changing our name and will be using a new domain....however we have alot of SEO juice from old domain name. We do not have access to the server and ecommerce provider allows only one domain name. We have domain names registered with go daddy and another registrar .....we want both to point to our new website and after enquiring i was told i will need to create redirects from old domain to new domain registrar ....I prefer not to spend time on google finding how to do this.... Note : this is not a www to non www redirect...this is a domain to domain redirect. I donot have HTaccess as no access to server at all not even FTP. ( ask for FTP access and i delete your bid) Only bid if you can create this redirect and both domains are coming to our new website. Thanks
