>and where a large pot of money is buried
This is obviously the problem here. When you say to a gentile "it's dark in here", you're not actually telling them that you want them to turn on the light for you, when they do so it's their choice entirely. If you said "Anyone who turns on the lights will be paid", that would actually be prohibited. I think the following article is pretty good (https://www.halachipedia.com/index.php?title=Summary_of_Amir...).
Isn't this a little like arguing that by telling someone I know is a hitman a physical description of a target and where a large pot of money is buried I haven't intended for him to carry out a hit? I don't think that would hold up in court (especially if it could be shown that this was an established practice for setting up a hit).
Do religious laws work differently?
