The simplest way would be to contact a manufacturer in China that makes tablets and work out a deal where they put your brand name on their tablets. Alibaba.com may help you find sources for that. The downside is that you will likely have little to say about the specs of the tablet. Also, I've yet to see a Chinese Android tablet that has decent specs and provides a decent experience. Going further, I'm sure that some manufacturer would be willing to work with you on the design specs that you have, but this will likely cost you. Another option is to start a business, raise capital (probably a relatively lot), and build up a team of engineers here. This would allow you to take a larger part in the design process, but will take longer and require more outside investment before you can even get a prototype out. I would look at the options available on the market now for white labeling, and build off that.
