So I was browsing my old .psd files, and I found one of the first sigs I made when I was learning PS, and it was shouting for animation. So here's it now, currently with an Osiris, but that can be changed to fit your needs. Also you'll notice that it has much blank space for a logo and/or text.
Now about pricing... My banks just got inactivity-wiped so I could use the cash, but I'd also welcome some ships that you don't use anymore instead. But for a GC sigmaker the best reward is seeing his work around, so if you plan to use it much and/or for a long time, prepare for an easy bargain.
