not only have i written site text for over 50 programs, but i am a woman and a native english speaker - 2 things that might be an advantage for your site.
on the other hand, i'm far from the least expensive out there.

of course, the less expensive writers are generally not native english speakers, and tend to write more formula porn text along with some humorous misuse of words.

i have plenty of references and do all sorts of writing, so i can easily show you samples actually in use on clients' sites. i'll pm you a couple.
