There are several national companies that book work with chains and franchises. They look for someone local to do the work at a bargain basement price. Often refered to as the MMM (Maintenance Management Mafia).
You could contact some of them. They can provide a lot of work if you are willing to work for wages. Once you get established, I would not keep that kind of work, but it can be OK when you really need the work.
In some sitautions they will negotiate a "travel fee" or allow some other charge to help increase the low base price they pay - usually 5 or 6 cents per sq. ft.
A few i recall right now - NEST from New Jersey. CleanWay is headquartered in Long Island NEw York but has branches in several major cities. Maybe some other guys can add contact information or more names.
Ther ar also some companies that sell protector warranties on new furniture. They can pay rather well if you have a high sucesss rate at removing the stains without damaging the furniture. They track how well you do on each job. There is Guardsmen and Guardian. One is located in Palm Beach Gardens, FL.
Another route is to get acquainted with the bigegest carpet cleaning supplier in your area. They will have an idea of who has extra work they may be willing to sub out.
