A large full warehouse gives you around £1.5million but with over 30 missions it takes time. This is from Reddit Crate Stats Thread.
So I filled a large warehouse solo running 3 crates each time. I kept stats on every run in order to come up with an actual value for money per hour. Here's what I got: My average mission time for all 37 runs was 7:31. I added in the 5 min cool down 36 times, added both, and divided the given payout ($2,200,000) by the total time taken (7.625 hours). This gives us the amount made per hour as $288,524 per hour. This is not net. If you buy 3 crates at a time at 18k, you spend $666,000 to fill your warehouse. Take that out of the final payout, and refigure, you get $201,180 per hour.
Lets say we have four members in a Organisation. One sits in an office with two warehouses, the other three are collecting crates.
They spread out across the city, you can do this in such a way so that at least one member is no more than a mile away from a crate.
1min 3 crates collected
3 min 3 crate delivered
4 minute 6 crates collected
6 minutes 6 crates delivered
If one member drives the van one member pushes with a car, the other goes to the middle of the city, ready for the next crates.
Another way of looking at it;crudely sourcing crates are going from point A to B and to C.
If you spread your members across the city A-> B has to be shorter.
