GTA Online: Gunrunning - Secret Alien Egg Supply Mission (Legit Way)

How to unlock the secret Alien Egg supply mission in GTA Online: Gunrunning

To achieve the goal in the fastest time possible we divided the team in three sub-teams (also abusing of some of our friends) working at the same time on sales, supplies and crates due to the fact that one of the required variables was the number "600".
Since we had our doubts on what the number was tied to, with almost a week of non-stop 24 hours grinding taking turns, we all reached the number 600 in sales, supplies and crates, and then we continued trying to unlock the mission during the 21:00-23:00 time frame.
