Handyman Job in San Francisco, California

We need a handyman for a doorknob swapout project! Basically we have 16 doors that need to replace the old unlockable knobs with lockable ones! We have the knobs ready all we need is a person who is quick and handy and has their own tools to get-er-done in an orderly fashion-ie keep the correct keys with the correct doorknob, and keeping the old ones together. We are offering $100 for the whole project.
