While I haven't gone through the entire process yet, I've found that having a few options and comparing them is key. It sounds like you’re already off to a good start with AsiaOne and Be Assistance. In my research, I stumbled upon a UK-based service, Newrest Funerals, which specializes in direct cremations. They seem really professional and thorough, and they offer repatriation services as well. Here’s their link if you want to check them out: https://newrestfunerals.co.uk/. I’ve read a few positive reviews about their services, and it might be worth reaching out to them for more information. I think getting a sense of how they handle international cases could give you some peace of mind.
