I plan to do the same. Here are my notes if they will help you:
ACE hardware sells pure ammonia. Dose to 5ppm. When water tests read 0 ammonia and 0 nitrite, do 90% water change to lower the nitrates and you should be able to fully stock after the water change.
The liquid ammonia tests that API make are measured in parts per million. It doesnt have to be exact. You can add from 5ppm to 8ppm to do the cycle. 8 ppm takes longer, since there is more ammonia to consume, and then more nitrite to consume bit it builds up more beneficial bacteria in the tank.
Heating the tank to about 85 degrees can also help speed up the fishless cycle.
