Unfortunately, we do not have the supplies or authorization to do so, but you might be able to find a shop locally who could perform the work, it is likely a cell phone repair shop could also repair your iPod, otherwise I would search online for a DIY kit. Kits online are around $70 depending on the generation, labor at a repair shop would be around $50.
The Apple store can also repair the screen outside of warranty. They would likely be more expensive, but would get better results.
