Passport renewal (expeditors?)

Has anyone used a passport expeditor in town? The ones I called want no less than six hundred to get the passport back in one week.

But the issue is I don't want to pay such a high price because I don't need it until end of October. But i can't get an appointment with a passport facility till three weeks from now so passport would be late by that time.

Anyway if anyone has passport expeditor recommendations or any advice at all please let me know… thanks
