Not like my opinion matters, just going to throw this out there to chew on. How much is someone else's time and talent worth. Who are you to think you can set that price?
That's not throwing shade at anyone, I'm just saying. Some people get paid for what they KNOW HOW to do, not what they do. Seriously, how many of us thought of actually counting leaf serrations on the 4th node, that has the even finger count on the leaf, during week 4 of veg and know that ONE is the keeper out of the other 100 that look just like it, out of 1000 or 10000 plants? And that plant when paired with another plant (found in similar fashion) will reliably give you the desired plant in seed form. The one people want when they buy that name and grow that as a seed? As a breeder once said, "you can know all about paint, and paint brushes, and painting canvas, but that doesn't make you an artist"
I think its relative. If you make $1500 a week, $1500 a pack seems outrageous, if you make $1500 a day, maybe not so much so. No one has a right to determine the value of another man's (or woman's) labor. The market will work that out.
