I work for an SEO Company in Manchester. at first glance your site looks fine and robots file is not restricting the robots in any way so there should be no issues with indexing or search engines finding your site. What type of work have you been doing off site? And what keywords? For a brand new site you must have patience, these things can definitely take a while.
One issue I did find is that your on site blog does not work. Dynamic content is important as they provide your site with a steady flow of fresh content which the search engines love.
