Grand total of 139,415 Rupees gained in total from that mission (4,300; 12,900; 7,900; and 12,900 for the four weapons I sold). Pretty solid for 20 minutes of work. Now yes, straight weapon farming can yield faster profits; I won't say otherwise. I'm just saying, I think this ain't bad side-profits for just focusing on KO-farming. Might as well make a little money while unlocking skills, right?
