I want to be a doorman ?

Hello I want to become a UK doorman but I have been in trouble by the police I have done some research and u can still get your SIA licence with a criminal record. I have had 2 cautions and a drink driving ban, 1 caution was when I was 12 for breaking and entering, the second was for drunken disorderly. Will I still be able to get my SIA licence ??
