Verification Help - Norton Safe Site

Please help. My site is www.sinnottflooring.com and it is hosted by Godaddy. I am trying to get it  verified with Norton safe site but it keeps failing. I do not have access to my root folder and I can't seem to get the meta tag where Norton wants it to be. I just posted it on my homepage and hope someone can help get me verified.

 

Also, how long do I need to leave this "tag" on my homepage?

 

Thanks
