Here's one trick I remember from some years back. You take the miscreant to small claims court. The cost is minimal in most jurisdictions. The miscreant usually doesn't turn up - he laughs at legal proceedings. However, you now have a court ordered judgement against him - which you can assign to another person.
The judgement is assigned (sold to) a member of a bikie club, preferably the President of the club. The President can then deal with it the way he wants to, perhaps see what one of the new 'pledges' to the club can come up with.
You're out of the picture, it is other people's problem now.
