Here are the three main things I can currently think of:
I know it isn’t the best solution or maybe even (a) solution, but try and have your TT at a height that doesn’t require bending/kneeling.
If possible, just take your TT to a reputable dealer for a precision alignment. Then, later on when the cartridge suspension has sagged a little,..I bought on of these... NASOTEC headshell alignment block. available through www.soundsofsilence.com . It’s a clear acrylic "see-through" block with etched reference markings that make adjusting VTA VERY EASY . It’s a good reference for visual azimuth as well. The good thing about it is it can be set on a lp next to your tonearm and is visually a real help!
All the best!
