Your web site has an option to have a Blog feature so there is no need for a custom design as it will look just like your site template unless you have already set up your site on Blogger.  In that case we can custom design a blog template for you or design one to match your already existing web design template previously purchased by us.  A blog is a must have these days to promote your business and each blog post is an opportunity to improve your rankings in search engines using relevant search terms.
