I don't see how a box of eggs is worth 3000 and a box of corn also 3000.
Considering 6 pieces of corn make a single egg, or when made into corn meal, 4 pieces make one egg.
Considering the 'mark up' for making the eggs yourself, this means that for one box of eggs, worth 3000 generally, I would be paying 2300 or so (575x4). Considering one of the biggest and slowest parts of this task is the collection of the eggs themselves, 575 is quite a fair price for a box of corn which isn't *too hard* to get.
If one box of corn was worth 3000, that would make a box of eggs worth over 12,000 trues.
The more powerful of you will scoff at this message, however the ones of you just starting may welcome the chance to make some easy money.
