Reply to Controller to Get!?

Hey guys so i recently purchased a Traktor S4. I am really glad i did. i want to get into making music tho, more than just mixing. I am not sure where to start. i am working on basic controllerism right now. I have no money currently but i will be getting more progressively so i want to know what to get. I have unlimited budget. it just might take a while to get there haha. I am looking to be making Progressive house, Trap, and a little dubstep. So yeah help me out? I would like to keep the money under $1000 for now. I will be getting ableton so assume that everything will be working with that.

Setup:
Traktpr Kontrol S4
