Darkgreensatincomeback

I have some paint chips on the pony I just got that needs some attention. The problem I have is that I cannot find the paint anywhere, and I do not want to pay a shop to mix it for me. I'm sure it will be a ridiculous price. I know there are some cans of it on amazon and eBay. But that is also pretty expensive for touch up paint. So any of the fine and wise people know how to mix it? Paint code is FU- Dark green satin.
