Any vouches on the effectiveness of these methods?? 
Yes, this one:
I have been sent a copy of this and the followings were my findings:

This is a good guide for explaining concepts. However it does not go into in-depth detail. He has covered multiple concepts( I won't describe them as "methods" since not all that was covered follows clear steps or guidelines) that can deliver good results, but without any actual "methods", only 1/5 - from what I can conclude - will correlate to the proof of payment(s) provided in the OP.
Could be written a bit better but guide is still somewhat brief and clear.
@OP
I apologize if you find this harsh, I try my best to be objective.
