Kokoro Dreams' life-sized android secretary's name is Phorone. She stands 175 cm and she has already starred in an anime where she was the protagonist. The big hope is that someday, she, and robots like her, will be able to replace real human secretaries.
"She is apparently powered by pressurized air and is capable of delivering human like expressions and can even talk," Slipperybrick says.
There are no plans of putting the Phorone up for rent yet, but there is this video (although the quality is not that great.)
Here are some more robot secretaries:
