Mario,
I'm kind of in the same boat. Where I have nearly perfected my Sword Fingers (and pulling blockages out of the body as far as "Level 2" goes), I don't have many opportunities to detect blockages in others. (since I live on my own)
Give this a try: visualize that someone you know is standing right in front of you. Then detect and remove blockages as you would normally level 2.
Someone please correct me if I'm wrong but I am pretty sure this is a Level 3 technique. (used for detecting/removing at distances) Since Qi is not limited by distance this should help you develop your Level 2 skills. And since you can do 'distance' healing, you will naturally develop your "close contact" healing of those around you.
