Hi Bunimouse1 and Welcome to Pharaoh Heaven
This early mission is to introduce farming and industry. You really dont have any opportunity to make money and it is best to just get the objectives met and go on to the next assignment.
You can place your farms with the speed at 10% and then layout one housing block near the top of the map where the immigrants come in. The immigrants head for the first for sale signs you set down. Get your laborers in the fields as soon as possible and build and staff a granary before the harvest. You wont have much to feed the people the first year, so stay small with the population.
Get your pottery industry going, your houses will need pottery and a little entertainment and religion to evolve. If you lay the houses out in a rectangle, the architect, fireman will pass by all the houses and you wont need so many. Use the road blocks to keep folks out of the flood plains, but dont block labor access to your work camps when you do this.
Just go slow and remember you are in charge. They will always want something.... and going in to debt to give them things is not a good habit until you can generate income to to overcome the debt in a short time.
Hope this helps, let us know how you are doing.
