Etsy or German local shop recommendations for period accurate clothing

Hello!

I want to create a late 10th-century kit for my enjoyment and medieval festivals. I've found what seems to be a pretty solid source for determining what is and isn't accurate, but I'm struggling to find online outlets to accumulate some of the gear. My wife and I are planning on attempting hand-stitched tunics eventually, but due to our lives right now, we're too busy for such projects. I'm also looking for an outlet where I can buy a helmet and haubergeon. It doesn't need to be perfect, but it must look right from 10 feet away. What recommendations do y'all have?

Here is the source I'm going off of: https://wiki.vikingsonline.org.uk/Society_kit_guides
