Earlier this month, on February 7, his Mornington Tavern was broken into by a crowbar-wielding thief who made off with several thousand dollars in gold coins.
The one-man crime wave, who also targeted other Mornington businesses the same night, remains at large.
Mr Miskimmin has now produced a ''wanted'' poster offering the reward for information leading to the arrest of the ''scumbag because I want to rattle a few cages''.
''A thousand bucks might inspire some of his criminal mates to dob him in as well.''
Asked if his approach would encourage vigilantism, he replied: ''Good - more of it should happen.''
He urged anyone with information to contact police in the first instance, and the offering of a reward had been checked by his lawyer.
That stand included offering a draw for a $100 meal voucher if people shared the wanted poster on Facebook, and ''hopefully it will go viral''.
He was also holding a sweepstake on when the offender would be caught.
Following the theft, he has upgraded the pub's security.
The investigation into the burglaries was ongoing, a police spokeswoman confirmed.
