Ditto what Brant said about needing to go out there and seeing with your own eyes what you need to see, finding out what you need to know and meeting who you need to meet in person. I knew nothing about the bike industry before I started Dialled Bikes and had zero contacts (to be honest, I don't know much more about the industry now and I can probably count the number of people I know in the industry on 2 hands), but a few speculative e-mails and a couple of trips to Taiwan filled that gap in knowledge.
You might find it easier to work with an agent out in Taiwan who will be your main point of contact and he/she can do most of the liaising with factories on your behalf.
Good luck with it, but go in with your eyes open. It's very easy to let your heart rule your head and it ends up being an expensive hobby rather than a proper business.
