StarCraft 2 map

I am looking for a some to help me with a Custom Map for StarCraft 2. There is another map I want to combine into mine and tweak. Ideally, I'm looking for someone with knowledge and experience in creating Custom Maps for StarCraft 2. If you're an expert in the game and have experience in map-making, please let me know. I'm sure we can collaborate on this project together and create something great!
