LF Plat 2 or higher Jungler for coaching

So the past week i went from S2-G3. my solo mmr was at plat 5 until last match its now at G2. I just got outplayed and out jungled by a plat 2+ player. I one trick J4 and I have my runes and masteries from King Nidhogg. For those of you who don't know who he is, he is the best J4 Player in NA. Honestly got out of S2 because of his runes and masteries, but I keep getting out jungled by high plat players. I would like some help to be able to go up against these high elo players. https://na.op.gg/summoner/userName=Lazyboyy
