Same-day rush service (L type)

Hello, I'm currently working in the U.S. (Miami, Florida), I have a French passport and would like to visit Beijing for 6 days.
I read that I need to go to the embassy in Houston to get an interview, which is fine, but I want my visa to be done the same day using the same-day rush service. Is it possible?
If not, what is the fastest way to get it done? Because I cannot afford to stay long or travel twice.
Is it possible to send someone to pick up my passport?

Thank you,
Mickael
