How do you make minimatica header site title an external link?

My Minimatica site is really basic – http://www.bigskybuilders.co. I currently have my site title in the header set to the home url. But I want to set it to an external link for people to click on . However when I change the ?php echo home url in the header.php to an a href in the title tag it tries to tack on the new url after the home url. So it will look like this now –> “bigskybuilders.co/www.tetonheritagebuilders.com/big-sky-builders” which isn’t a page on my site. I really want my site title just to send people over to http://www.tetonheritagebuilders.com/big-sky-builders.

Can anybody help me out with this site title link issue??? I was able to get my header banner to be an external link but can’t figure this one out.

Thanks!
