Well you need to align the dish/motor assembly.
As said, the later pics of your dish show it being too low, so set it back to 22.5 as a starting point.
Then, you need to trim the azimuth (direction) of the system by moving the entire motor/dish assembly around the mounting pole and you need to trim the dish elevation by making small adjustment to the dish bracket.
But if you've got everything else apart from the initial dish bracket angle more or less ok, it's likely that you'll start to get a signal by altering the dish bracket alone.
Once you've found the Satellite, then you need make only very small adjustments to get optimum Strength and Quality.
I suggest that you stop for now and consult all the guides previously linked so you are clear in your own mind what you are about to do.
