icon distribution packaging

i need you help guys. I have designed numerouse icons.

I need to package them for sale into these categories Normal, Hot, Disabled, Gray and these size 16x16, 32x32, 48x48, 128x128, 256x256.

Do you know any software that can do this automatically for me, or do i have to develop my own.

Am average programmer in vb.net. But not an expert in graphics programming.

please give you suggestions

Looking at a random site or two it seems like good old PKZIP is the standard way of distributing them.
