I think that if you got another male rabbit then the chances are you would just end up with two rabbits that were single and couldn't have any interaction with each other. I have 10 males here and mine would fight to the death with the exception of Dawn and Hope who live in a trio with a lady friend. I have experimented with bonding options but there are none.
It IS possible to bond males, but is only really worth a shot if both are neutered, however, there is a high chance that it wouldn't work out, also a high chance of fighting once bonded and generally a lot more risky.
A spayed female would be the best way to go.
Is your bun neutered? I'm presuming not? That might be a good place to start to ensure the most successful bond in the future.
I wonder if maybe you coud contact the 4H breeder and see if s/he has any adult girls that she is planning to not breed and could sell you. Then you could look to getting that bun spayed. However, there is the risk with any bunny that they won't bond and could fight.
Are you happy to potentially have two loner buns together?
Could you please put your location in your profile because you will end up with more specfici advice. In this case you might find someone who can help you find a rabbit.

If they have lived together since birth they will not fight most likely.
I also just want to say that I personally disagree with that. Whilst it is possible that they won't fight, there is also a high likelihood that they will fight (even if neutered as soon as the balls drop).
