Reply to What to get what to do??!!

So I am new to the Dj scene and well pretty much new to everything that is electronic music. I've listen to dubstep for like every and I love EDM and house music. recently I've fallen in love with trap and finger drumming. When I discovered finger drumming I immediately bought a midi fighter 3d but now I want to progress and do bigger things. I have a soundcloud and its www.soundcloud.com/gagnon23 go check it out if you want. but I just want to know what to do next? I want to make dubstep and mix songs but I don't know what to even buy.... I'm getting my taxes back soon and I'll get around $550 so I need to know something affordable and good. So if anyone has any insight they would like to share with me that would be awesome. Thank you everyone, BTW my name is Jacob.
