Okay, this is as step by step as I can, with an even different strategy. I can finish in just over 5 minutes so it should allow plenty o' time.
Use worker to build farm in open space by pond.
Buy a scout.
Place merchant and defender at mill by pond for now.
Scout's now ready, have him start digging for money.
When farm is ready, buy another worker and have him build a lumber mill by the silo.
Move the defender to the farm and buy a scholar for the farm.
Lumber mill should be ready, leave a worker there, add a defender, another worker and a merchant (adding workers to the farm as needed to allow for the extra people)
Upgrade the farm to one star as soon as it's ready. Add a second scholar as soon as you can.
You should be close to having 700 coins by now, when you do, move a worker from the lumber mill to the mine, destroy the mine and build a market there.
When it's done, move/add 2 merchants and a defender there. Convert money to wood to keep upgrading the farm.
You should be able to add a third scholar to the farm.
When the scout finishes digging, add him to the lumber mill.
When the farm hits 3 stars, go ahead and destroy the lumber mill by the pond, take a worker from the lumber mill by the silo and build a mine by the pond.
Upgrade the farm to 4 stars, move all scholars (plus a new defender) to the mine, order up 3 cultivators, selling off workers from the mill as you need to for room for the cultivators.
While the cultivators are in process, order up 2 more scouts as well (converting lumber to cash as needed)
Upgrade the mine as it becomes ready, then when it reaches 3 stars, sell off the scholars and replace it with your 3 scouts.
