Junglers I would recommend are Amumu, Gragas and Maokai.
Amumu has pretty good early ganks, fast farming, and great teamfighting ability. However, you are somewhat vulnerable to early counterjungling. I'd recommend building tanky, with a Sunfire Cape and/or Liandry's Torment for damage.
Gragas has really strong ganks early (a knockback with stun, a ranged slow) and his ganks after level 6 can be horrifying (use your ult to get them away from safety and into your teammate(s), even when they are under tower). He's also pretty mobile and transitions well into a tank. Main item would probably be Iceborn Gauntlet as he makes good use of Spellblade, the mana, and the armor.
Maokai is a heavy ganker with an early roots+gapcloser, slow, and a knockback. He scales very well into the late game as an aura-bearer (Frozen Heart, Locket of the Iron Solari, etc). I would recommend Boots of Mobility on him to get in range for your Twisted Advance and, if you want damage, an Iceborn Gauntlet and/or Liandry's Torment.
Though, if you like Evelynn you may also enjoy Rammus. Rammus jungles typically rush Boots of Mobility and Homeguard which, when combined with powerball, allow him to cover his teams side of the map easily. You mostly just level his E for the taunt duration after a couple points in W for farming and gank pretty much constantly. If you have teleport as well, your lane ganks are really hard to avoid.
