First of all, I believe that this is not the place to complain. All mappers of all modes have this same problem of finding BNs, so you're not alone.
Modding queues in this section of the forums are for people to post that they want to help, and then people request on that post for mods. Rules on how to use the forums can be found here:

If probably means you met a minimum of 5 people to mod your map, but it's a matter of quality. It's better to have modders, regular players, mod your map for any tiny details before you contact a BN who most likely will not not nominate your map and rather rip into every detail they don't deem rank quality. Your map is short, yes, but because it's so short, there's no room for errors.
