The copy needs work on the front page. Saying "No Errors" makes people think of errors. You don't want that. Try "Perfect Prose" instead.

Likewise, "worry-free" has the same negative effect. Instead, say "Express Service" or whatever.

One more thing, samples. Have a few samples or examples for people to see.

Overall, pretty good. That's my .02.

P.S. I wish you the best with this!
