Looking at the Stormcast box, here is a list I came up with.

Skyborne Slayers 140
Lord-Celestant 100
Judicators 160
Judicators 160
Liberators 100
Liberators 100
Decimators 200
Protectors 200

Celestant-Prime 360 (?)
Knight-Azyros 100
Prosecutors 80
Dracothian Guard 240

Total: 1940


This would use the Battleforce, one start collecting box, two boxes of Judicators, and one box of paladins.

Not sure what to do with the last few points. Probably a gryp-hound, but that requires an extra $40 kit, which goes against my building-on-a-budget planning.

Not sure which Dracothian Guard are best. I am leaning towards the fulminators, since they have the bonus against shooting which would be useful as one of my 3 units that starts on the board. On the other hand, the Concussors are more reliable when they don't get the charge, and the longer range on the lightning means they can better help snip enemy heros and stuff.
