This is a delicate subject, but if you have 9 twenty-somethings working startup hours... that's basically a dorm. Consider frequent janitorial service.
Incidentally we're looking to share an office near Mission or Noe. If anyone wants to sublet for 2-3 people or maybe go in with us on a lease, drop me a line.
If you are trying to move faster, I'm a bigger fan of the 'work saturdays' ideology. Try to do 7-8 hours 6 days a week. That worked much better for me.
