It sounds like you have live plants. If you do, and if you also move wood and plants from an established tank, you will be able to add some fish immediately and there will be no cycle to speak of. The plants consume a lot of ammonia (as ammonium), and what they leave behind, the nitrosomonas bacteria grab, and the bacteria will be plenty on the wood and plants from an established tank.
I have set up many tanks with plants, always introduced fish the first day, and never had ammonia or nitrite above zero from the first. Just don't overdo it with the fish, a few at first, then a few more after a couple days, and so forth.
