I used to work for a company that imported goods from machine. Most of them were custom PCB and PCB assemblies. We didn't have any major problem but we had to change manufacturer two or three times due to quality issues.
I'm not sure all those numbers are correct. I was born in the Dominican Republic and I can say that the time to open a business is least than 20 days.
Besides, there are some companies offering "packaged business"s with legal fees, registrations, and other paperwork ready. You can buy one of those and get up and running in 24 hours. They take care of transfering the company to you.
