Don't do it. You are wasting your time and it's very inefficient. In China, there are factories that have pre-rolled boards that will give you what you want at very cheap prices. Build a prototype, then get in contact with a chinese sourcer to find you what you need. You'll need to buy in bulk of about a thousand pieces or so - but on the positive side, you can get your frame and so on done there also. Anyone who is even thinking of building such a device themselves is grossly inefficient. If you need a company in china, send me an email I'll direct you to one.
