410265 Article Template

Hi, I currently have many articles already on my site and I used "content templater" to make my article templates... however I just recently discovered that you can add your own permanent article template into the CSS style sheet.. If someone can help add this template in permanently for my articles and make it work for my existing articles (if possible) without me having to manually go through them all, I'd be truly grateful. This is what all my articles look like (different picture and information of cos) *look in attachment So basically, I just need to the article template (i already have the template) permanently into all my articles (if possible or at least for my future ones). *if you are unable to make it work in my existing articles, then at least make sure it doesn't affect them. Please post a reasonable bid, I don't have an enormous budget. I use Joomla
