hey man 18+ life is good and bad Club will always have there own gear,only place that wouldnt would be a Pub or something that isnt specifically a Nightclub... and most clubs are using CDJ's you just take your CD wallet full of your favourite tunes to mix, or music that the club wants All the new CDJ's coming out have USB inputs so you can either take your Laptop (not recommended) or USB sticks with your tunes on them, very easy, i do both....just not in a club ....yet and as for getting the Gig you just gotta be confident,good at what you do, and make sure you talk to the Promoter/organizer, be polite and not scared, you dont wanna walk up stuttering n shitting your pants....and make a demo before hand so they can see what you can do if they ask hope this has helped
