Looking for someone to clean up rig/shape key on model

I am not the best at rigging and already rigged my model but I need it to be cleaned up a little as well as making a shape key for mouth for talking and one for like a shocked face (O like mouth shape). If anyone is willing to help out, they will be credited in my Fan Music Video I am working on that it will be entered into. Also if anyone knows how to make the dress part that hangs down able to run along leg when she moves, even better.
