I got you brah:http://www.internmatch.com/guides/cover-letter-example-and-templatehttp://www.internmatch.com/guides/resume-templates-and-visual-guide
I suggest making it look pretty as well as places like that would appreciate creativity. If you give me your email I can give you an example of my resumes (resumes because I have different ones for different places).
Example cover letter I've done:
Dear CrashPad Boston,
On my daily search of firms I could see myself gaining life and work experience in, I ran into yours. CrashPad Boston exemplified everything I loved. I am constantly doing small projects to entertain myself as well as create something I believe will shock the world but I always thought it would be better if I could work with someone who shared my views. You provide what I've been missing plus I like your website layout too. I believe I would be an excellent addition to your team due to my skills and qualifications I have gained through my studies in Communications and New Media. They include just to name a few:
Strong Research Ability: As exemplified by Google Sites website on the follies and positives of attending concerts for my "Using Internet Communications" class at UMASS.
Creative and Quick Learning Nature: As shown with my numerous music and video programs mastered.
Strong Communication Skills (Verbal, Visual, and Written): Which were acquired through WHUS Radio Training program, Intro to Video, and focus of my major.
I believe these skills would put me in a position to help the growth of your company as well as myself. I look forward to hearing from you.
(insert your name)
Hope this helps
