Finding a pre-reader/proof reader for my Fanfic

Well it has clearly been a while since I have written yet another chapter for my story "A Feudal Mix Up." This was because someone had suggested to me that I look for a pre-reader. It had been a while and I could not seem to find anyone and so I had managed to find two people who could help me with my story. However, it appears that one of them is just plain being a grammar/ plot Nazi with me when I try and even explain my story after they gave their input which was good. Communicating with them about my story ideas is another story all together.

Anyway if you are here about my story, please be sure to PM me if you don't understand something and if you have an attitude about my ideas, don't contact me because we are here to help each other be better writers. Is criticism important? Oh yes? However, please note that if you can't see eye to eye with someone on a certain issue, then don't bring it up.
