Besides that, it looks unprofessional when a business doesn't bother to remove the links to Wordpress and Theme creator from their website.
Nevertheless, every Wordpress theme comes with a built in link to Wordpress in the footer, and most have links to the company which created the theme as well.
For $5 i will remove those from your website.
Remove "Powered by Wordpress" link
I will manually remove the "Powered by Wordpress" and the theme links from your website footer.
