If you can make a doll that looks like that then yes, I would switch careers as as soon as possible , I know hundreds of people that would buy them from you tomorrow for more than $2,000.00 each!
I don't see any difference with the other $50 doll with much better quality which you can buy at shops. Well perhaps yeah maybe the only difference is that this one looks like Angelina Jolie.
There is definitely good money in dolls. I had a neighbor that paid $300 and $400 for Barbie dolls that had originally sold for like $40 a few years ago. I know that's no where near $2,000, but it's still ridiculous---my cars don't usually cost $400!! Sad huh?
