My second toon (a mm) is at lvl 18 in southwark so when you catch up I'd be willing to finish from there to stonehenge and level with you for awhile in SH.
Welcome!
For an evoker, I would go either fire or bone for the first 18 levels. You can't go wrong with demonspine. It scales well and is still a good spell at high levels even if you go hellfire/flameshards.
This is my build right now - I respecced so I didn't have to worry about lower levels but this will work for you.

Dual focus is obvious
You can spend the extra 7 points on whatever you like - maybe some venom armor or +1 point in the summon ember so you can get +7 on a weapon switch with dual +3 summon ember foci.
EDIT: I have a lvl 18 focus with +1 arcane legion which is like a self-rush. It's way OP. You can also look for a +1 hellfire focus as well. Once you hit a level where you can use hellfire or legion it'll go really fast.
EDIT2: Some people don't like arcane shield - I like it because it's instant 2600 shields whenever you need it. It is great for sh runs and catacombs because you don't get procced with stun or poison or phase or (worst of all for a fire evoker) shock. If you get shocked you can't use your spells or arcane shield so it's annoying.
