This forum is not suited for it. So don't expect any mods by asking here.
Best chance to get a mod is to camp the
Modding Queues in the hopes to find a open queue which will accept your request. Be sure to read the last post (and the OP) to make sure you don't break any rules.
Most effective way to get a mod is to do Mod 4 Mod (M4M) in #modreqs, a lot of users accept it and a good way to learn mapping is modding other peoples maps. (not sure how to start modding another persons mapset? try reading
lolcubes guide to General and in depth Modding Procedure)
You can also ask people directly in game if they are accepting mod requests, but remember to be polite, not everyone accepts modding requests like that, so don't be disappointed if people turn you down.
Last but not so effective is to just post your requests in #modReqs, hoping for a mod.
Good luck with your mapping.
