Mike Hunt
dammit!!
DJ Phil Mianus. DJ Mike Hunt. DJ Mike Hawk. DJ Connie Lingus. DJ Eric Shun. DJ Harry Beaver. DJ Kenya Swallow. DJ Willie Fisterbottom. Something along these lines would work great to get you the money$ and the bitche$.
I crack myself up sometimes.
EDIT: Sorry Willinfluence, didn’t mean to copy you.
Serious answer - unless you’re playing a keytar or wearing an animal mask over your head (or have some killer USP, in which case a name should leap out at you anyway) then use your own name.
Using half your first name and adding a 'ster at the end 
use a nickname your pals gave you, not one a clingy ex girlfriend gave you.
Mr. Floppy?
Or maybe you use your first pet’s name as your first name and the street you grew up on as your last name.
