Answer
(Fatwa: 2572/1930=H/1429)
(1) Your question is unclear, which amount does not the organization want to make known and want to take benefit from? And the benefits are achieved? Does not the organization cheat anyone in this dealing?
(2) The mentioned organizations are appointees (wakil) of those wishing to perform Qurbani. If they have given those organizations authority regarding meat, then it is allowed for the organizations to mix the Qurbani meat and distribute it as per the wishes of the people doing Qurbani. This is neither a type of selling Qurbani meat nor similar to it.
(3) This is not lawful. It can be allowable thus that people doing qurbani should tell the organization to purchase animals without skin-dealing and sacrifice them on their behalf. After sacrificing the animals, when the skin is peeled off, any persons is appointed wakil to sell the skins, (no matter if this person is a member of the organization). The appointee will sell the skins (though to the organization) and spend the money according to the wishes of people doing qurbani.
