I think in your budget, I would rent for a while. So many places rent decent gear for cheap now, I think you'd be better off renting stuff for a while until you have enough money to buy gear that will last you longer and perform better.
What kind of EDM are you talking about? Funky house? Dubstep? DnB? Electro? Techno? Trance?
In front of how many people?
I play dubstep and I used to have a pretty big portable rig with some friends for doing raves, and now I play at clubs mostly, but I have a small mobile system for playing at small parties....

I can do a household size room and really make an impact with this little system, and everything fits in one trip in my SUV, even with my vinyl and decks. Sounds better than most hifi systems too.
