im not the one to give you advice here but i can suggest you to talk that to those other djs and maybe you can get one of them to be like your tutor.
About the money, well, i guess what you can do here is decide what kind of dj you want to be…
Theres a whole series of articles posted by D-JAM talking about the different kinds of djs out there. If you are planning to buy lights and audio then perhaps you want to be a mobile dj, in that case maybe you should start saving some money. On the other hand if you want to be a club dj i guess it shouldnt be a problem since clubs have their own lights and audio system. Correct me if im wrong.
