Cotton company costs 10 euros to buy it from game and needs :
1. machine Q1 is enough and later depending sales etc. you can buy a Q5 .
It costs 6-7 golds almost in all countries and the work it does is to gather cotton in the regions that produce cotton.
The machine Q1 gathers 1000 cotton before it decays.
2. You must open branches [costs 1 euro ea] to the regions that have cotton
3. You need at least one worker to work to gather cotton in the ratio of :
1 cotton =0,2 hours [wellness 100%].
That means that a worker with 50% welness will make in his 8 hours of working:
[8 hours / 0,2 wood ] x 0,5 wellness = 20 cotton .
The cotton company dont require a license and dont need materials cause is a raw material company that means gathers materials dont produce products.
Tip: see your countries regions with cotton and if are low buy a Q5 machine and open more work places.
