This sounds like Hetepsenusret, but I cannot be sure. In Hetep, you have to max out sales of Papyrus to Dakhla Oasis as early as possible to get enough money. They only buy 2500 sheets per year, so make sure that you have that amount to sell, as 3 trade caravans will come from that city. If you can get Ra on side early on, he will have a chance to increase trade quotas temporarily, so Dakhla can temporarily buy 4000 sheets.

As soon as you can, you must also expand your housing and tax your citizens to boost the income more. Make sure your city is stable before growing it, and take your time to expand. Rushing your expansion will result in failure, so build slowly and evolve housing quickly.
