How difficult is it to start-up?

Hello,
 
I am a young entrepenuer that has been making custom patches for people like the military, paintball, etc. I noticed that 3D PVC patches made via PVC Injection Molding are really gaining popularity and I'd like to start offering them for sale. But I can find nothing on the internet about it! I can only find a few companies that even sell machinery, and they are all in China. I'm in the USA and worry about things like support and supplies if I ordered from China! Especially since I can't even get a sales person who speaks decent english to tell me the price!
 
I just want to know what the learning curve for someone with a great understanding of vector and raster files and design in general. Then the price to setup everything needed to get started making 3D PVC labels. Is there a company in the USA that can provide me with this information and the start-up costs for this? Or any where on the internet with introductory information on the business? I am so lost but really interested in getting into this business.
 
Thank you in advance for any information!
