The fast way is to post an ad for your services to Craigslist South Bay GIGS Labor detailing exactly what kind of labor you can do and whether you have a truck to move things. I know you ll get jobs like that.
Advertise your labor on a sheet of paper and repeat your phone number many times (so interested persons can tear it off) and post it on a laundromat bulletin board??Describe briefly what you can do. I ve seen that in laundromats here in SF. You can offer your labor to help in moving but try and make sure they are nice people and won t stiff you.
