Brushing up 2D effects and animations in Unity

Hello, I am looking for someone to brush up the effects and animations for our game. The characters are animated as FBXs, so you will need access to a 3D model editor. The effects use a combinations of sprites (either static or animated), and particle effects. You will NOT be required to design new effects, only modify currently existing ones. If you are interested, please contact me for more details.
