If you do send a letter, make sure to include a cover letter. (Wow, business writing section of Lit comes in handy.) The cover letter is just a short introduction, designed to pique their interests -- the company likely gets tons of mail, a lot of which they don't want to waste their time on. Explain (1) why you are writing, (2) who you are, and (3) what you want. Make sure to include contact information and to thank them for their time. I'd scan their website to see who to address it to in particular.
