I respectfully disagree with the idea that an ammonia spike is somehow necessary to have a successful bacterial population in a new tank. Assuming you're using cured live rock, you will be fine to begin stocking the tank slowly with clean-up animals, corals, and a modest sized fish. Here's my thinking:
Back when we used artificial media to grow bacteria (undergravel or wet/dry filters), we needed an ammonia source to feed an essentially sterile environment. This was usually done with damselfish, which may or may not have survived the process. The bacteria slowly reproduced by feeding on this produced ammonia.
However, once live rock became the backbone of biological filtration, the "cycle" didn't occur anymore in the sense of bacterial colonization. We go to all the trouble to bring live rock in because it already has all of this bacterial content. The curing process, in which all of the associated sponge/algae/animal matter that doesn't make the trip dies off, is enough to ensure that sufficient bacterial mass stays viable to maintain biological filtration.
So, if you're curing your own rock, wait for the curing to be finished- you'll have more than enough ammonia to go around. If the rock is cured already, avoid the dead shrimp or other deliberate ammonia source and just add animals slowly enough that the ecology in the tank can support them- you'll see no detectable ammonia if the rock is really cured properly. Stocking slowly is something you should do anyway for the sake of building up biodiversity, which is perhaps how we should think of "cycling" in a modern reef aquarium. Good luck!
