Hi Ladies! I hope you don't mind me crashing your board

I'm not sure where else to go to get this info.
Long story short, FI and I are moving to the Bay Area this August. We're driving from Chicago to San Francisco, staying with a friend for five days, and then flying back out for a Minneapolis wedding. During those five days, we need to find an apartment in San Francisco and coordinate our moving truck arriving before the wedding. Gah.
I've head of friends in Chicago who have used apartment finding services with great success. I've looked for some online, but I'm having a hard time finding a reputable service. I would appreciate any suggestions or recommendations! Ideally, I'd be looking for something that would take down our specifications (neighborhood, price, # of bedrooms, etc.) and then show us a bunch during a 1-2 day period.
Thanks so much for reading.
Oh, and if you have a friend looking to move out of a 1-BR apartment in the Russian Hill or Nob Hill area in September, let me know
