Here's one of several sites that gives some great "readiness" checklists. I wonder whether your daughter is truly ready for success yet: http://www.parentingscience.com/toilet-training-readiness...
In my own experience and that of several families I know, once the child is ready, she will willingly train herself, with just your support and a bit of coaching on the how-to's.
Kids who are ready can sometimes train in one, two or three days, or usually not more than a week or two, without the parent having to watch and coax and set timers and give prizes. A child who's ready for success will go for it, just as when they learned to walk or talk. It's a completely natural step toward maturity.
I have heard of a number of kids who trained much younger in three days, but backsliding is common. They often hit a wall when they realize they are supposed to take responsibility for this annoying intrusion for the rest of their lives.
Please know that night training and poop training are completely separate steps for most kids, and each can have its own set of challenges to overcome. Many children don't develop the bladder control or ability to wake at night from bladder signals until they are well into grade school.
