Design a Logo and Two Characters

I am working on a table top game and need a simple logo (for the backs of the cards) as well as 2 to 4 characters made. For the logo I'd like 4 dots in a diamond shaped pattern, however each 'dot' is more like a crater with light beaming from it. Imagine 4 glowing meteors crashed into the earth and created 4 holes, streaming with light. The colors I'd like are Green on the top, Red on the right, Black on the bottom, and Blue on the left. As for the characters, I need a Miner and a Teleporter. The Miner character would be mining in the craters as mentioned in the logo. I need two Miner characters - one predominantly green (clothes) and one predominantly black (clothes). They could be the same image, just different colors, or two different images/poses completely. For the Teleporter character, I picture some sort of space suit to travel between places via portals. I need two of these as well - one red and one blue. Again, they could either be the same with different colors, or two different poses. I would like it formatted in png. Thanks and I look forward to your help! -Adam
