A travel emergency here...

I have a flight from Boston to Japan this upcoming Wednesday (8/1). Today I found that I have lost my passport. The house has been flipped up side down and I still couldn't find the passport. So I logged on to travel.state.gov to see what kind of expedited passport service they have. There's not much help available: There is a number to call (877-487-2778) to schedule appointments for travels within the next 2 weeks. But when I called, the automated system got me an earliest possible appointment of Aug. 10th.

So I googled around and found these expedited passport services (like passportsandvisas.com, visahq.com, passportsplus.com) that list detail instructions on how and what to Fedex to them to get a passport within 1-2 business days. Has anyone used this kind of service and actually received a passport that quickly? I am desperate here and would pay the fee they are asking to get my passport in time for travel.

Anyone know if these services are trustworthy?
