Once you prepare your resume, you need to move on to the cover letter. No surpise, Mediabistro Resume Revamper Alex Twersky has good advice:

A cover letter is not a design exercise; it's a vehicle to concisely and coherently introduce the reader to the subject of your resume and why they should read it. As such, the cover letter should not restate the resume's content (a common error) and furthermore should contextualize the experience about to be presented in the accompanying resume. As such, a cover letter's design should be kept simple and consistent with the resume (they can even share the same header presenting contacting info). The content of the letter should focus on enhancing the reader's understanding of the candidate's work experience, and adding focused reasons why the candidate specifically wants to work for the target company.
