Eye droppers and similar things can be found in Wal Mart and any store with a pharmacy department.
Look around for one that has black lines on the side. These will tell you how fine a measurement you can get.
An eye dropper that holds a total of 1 ml will usually be marked down to 1/10 ml, or .1ml.
I use syringes without needles, picking them up here and there, friends in the medical and veterinary fields (Try a feed store, or even a dog and cat place, look in the section for nursing orphaned babies and other medical stuff).
I have syringes that measure up to 60 ml.
Turkey basters may also be measured in ml. They are not so accurate, though. Fast, to dose the big tanks, however.
I have kitchen measuring tools that measure both ounces and ml. ranging from 1/8 tsp to 1 quart.
The tools are out there, just gotta look!
