Cover Letter Creation / Resume Overhaul

Hello, I currently have a resume which is up to date, but I would like to rewrite it and make sure I include every single skill, achievement and piece of knowledge that I have, which I will provide to you. In addition to redoing my resume I would like to have a professional persuasive cover letter written which will attract any potential employer to hire me. Although every cover letter needs to be custom I would like a template made that would be universal. Again I have all the information and resume already created. This just needs to be rewritten and made into professional formats. Thanks, Drew
