Are you cocos2d expert?

Hi all. Now I need a person who can build a awesome particle effect using opengl or cocos2d. I will provide the sample video which show how the particle system works.

If you can make this effect, you can use any opengl code. If you are expert, it will take 2 ~ 3 hours at the outside. I look forward to find a good person. Best regards! Jang
