Do your own homework!

In the end you'll ride a bike that you'll be proud of and/or you'll be proud to sell to your customers. The Chinese will make it as good or as bad as you tell them to. Not being well versed in frame design and manufacturing will only work against you in this process. There is no harm in studying the plans but try to understand why that frame manufacturer came to the conclusion they did in designing their frame but change it and make it your own.
At the end of the day all frames are pretty much the same but its the tiny details that make the ride unique.
