Auto auction?

im located here in dallas tx. if i could find someone that would let me go with them to a dealers auction and bid on some cars would that be possible or would that be too much trouble for someone and who would be interested in helping me where would i go to talk to someone and what would they charge me for doing this i would pay.|||As I said in my other post on this exact question, $1,000 would be fair if you knew someone who would take you there.
