I can tell you, from installing satellite systems for almost 14 years, that having a good, stable, and plumb mount are the keys to getting a satellite dish aimed easily and correctly. I recently aimed my first GEOSATPro 36", which looks like what you have. The elevation was a little hard to determine on mine, because the white mark they referenced in the documentation, was obscured by the nut on the elevation adjustment. I figured out it's roughly the metal edge you can see through the elevation adjustment slot. Anyway, point is, don't skimp on the mount, make sure it's plumb, cement it in, as long as you have good LOS (Line Of Sight) you should be able to tune it in. I'm not familiar with your receiver, but mine showed no signal or quality until I ran a Blind Scan. Ku FSS signals are pretty weak, so it takes a bit of fine tuning to get decent signals on them.
All that said, I'm very new to this, and this is just my advice as a Dish/DirecTV/HughesNet installer.
Here are some pictures of mine, these are bolt hole A, about 50 degrees elevation on scale A, just to give you a reference. My LNB is also only -2 degrees for polarity, so pretty much straight up.
