If you can't find a suitable
badge on eBay, it's going to be a dealer job; it's a very niche part to find from anywhere but a dealer, to be honest.
If you give Sere Motors a ring, you'll probably find the price, including delivery, to be quite reasonable. The quality of an OEM part is going to be a good bit better than you'd find on the eBay too, I'd suggest.
