I'd definitely look to add some more content. It's looking very good and professional, but people visiting the site and having a look around might well see the last news being nearly a year ago, and the last blog being seventeen months ago, and get the feeling that the site is a little bit dead. If you're going to have a blog and a news feed, you do need to make them more dynamic.
This isn't a criticism, as there has obviously been a lot of work put into the site and it looks high quality. It's just that if you're looking to bring in business in the present day, then some updating of the news and blogs will make it look more like you're "open for business".
