The first thing I want you to do is build 45 construction sites (You’ll have to build them 5 at a time as you won’t have enough money for all 45 in one go) and then build two turn's worth of farming zones (should be 40) then with the remaining free land build construction sites.
Then expand 1 turn and build a turn's worth of farming zones and with any spare land build construction sites.
Repeat this last process (you might have to expand more than one turn so do that) until you can build 30 buildings per turn (bpt) once you are that point just expand and build like that til you have used up 198 turns. You can see how many turns you have used on "Your Overview".
At this point go to the public market and then this bit is your decision but I would suggest putting all your food on the market for $100 (the max). This means it will take a long time to sell but will get you the most money, this early in the set it might be wise to sell for a lower price, but after your food has been on the market for a certain amount of time it will start to decrease in price anyway so its swings and roundabouts
After you've sold your food its pretty much up to you what you do, but I would suggest not using more than 199 turns as you will come out of protection, you can do that and then talk to me before going out of protection.
This is just what I've been telling my recent noobs who managed to finish 16th last set, seemed to work out ok for them
. As for the next 100 or so turns, do what you want, justmake sure you have like 1k tanks after you've finished taking your first set of turns oop.
edit: After I wrote this (beginning of NW) I since decided that 30 bpt is too low, but told the individual player to do what they want as far as bpt goes.
