Unless you have been DJing for quite some time and are fairly well known, the likelyhood of DJing at clubs is not likely. Keep trying the demo sending though, you never know. Ur best bet is to try bars and just taking ur records and demos out there and showing your face pretty much here, there and everywhere.
There are thousands of DJs out there so persistence is ur best bet, but also kinda of a drawback. Most promoters and bar owners do get ticked off by DJs constantly nagging bout work!!!
Anyway, hope this helps, but as you can see its just like being back in the UK with regards to getting work!!
Any more questions don't hesitate to PM me.
