Revisions To Corporate Introduction Letter Required

From the attached sample template we require it to be revised into a slick, professional, corporate and polished introductory letter. Not jumbled or too colourful. The target audience are going to be in senior management / executive positions in companies. They will be educated, sophisticated, short on time and more than likely, smarter than your average Joe Blogs. The look and feel of the letter needs to strongly reflect this. REFINEMENT IS KEY!! VERY EXPERIENCED FREELANCERS ONLY - NATIVE ONLY ENGLISH SPOKEN WITH A HIGH COMMAND OF THE ENGLISH LANGUAGE
