Orchmelia on IG is the one I use. There's a whole thread about her in the Chanel Shopping subforum. Be aware that because she doesn't charge a lot, she doesn't really provide the whole "service" aspect. Like you basically tell her what you are looking for, and she'll help you find it. I believe for some bags she might require a deposit that is refundable if she isn't able to find the bag for you. She charges a deposit because I understand a lot of people have asked her to find bags for them and then they back out once she's found it, so this just prevents time wasters. You pay her directly, along with her fee. You should do your own research separate from her, for example on Youtube or Purseforum. She literally just helps you find bags and might answer a few basic questions, but that's it. If you're looking to get good service, you'll probably be disappointed with her, but you get what you pay for (basically a procurement service). I've bought from her several times and it's usually very straightforward, and I get a beautiful bag without having to search for it myself.
