Hi 1irene, welcome to the pond. When I start this level I hire a scout and put her on the gold, have worker build farm then demolish lumber, put lumber on the right side of the screen. then put worker, defender and merchant on the farm, hire a second scout to harvest gold. When you have 700 build market, move merchant to market and hire people to start the upgrading of the farm while adding workers to the lumber and the farm. towards the end I have three guys in white robs upgrading the farm and one on the gem mine upgrading it. play around with this configurations and see if it helps at all.
