I perhaps want to just sort of move your brain bit out of the bos for a second and just perhaps change your stategy a little bit, and there's good reason for that.
I'll start here first. Basically... More > your whole stategy - I want to talk about. If it's going to be a cover letter then it should actually read like a letter - as if you were actually writing this letter to a friend.
You knom, if you don't have their name then "Dear Friend"? OK?
And no letterhead at the top. You can put your business name down the bottom if you want - I mean I'm just talking about actually doing this in your computer program, where you actually, down the bottom, type your business name and a phone number if you want to.< Less
