There are a couple things you can do to conserve cash. Only learn the skills at first that you need or are going to use soon. And convert your nobles from Contract to Fear or Oathed status. Top of the page Noble Points. Up to you, preplan what direction you want your faction to take.
Some factions are magic intensive, others go for beastmasters.
Some want to explore and quest. Some go for a combination of all and some go for just a few Oathed nobles. So like I said, Preplan what you want to do. Top of the page To Fear , Contract or Oath. To save money, I suggest converting the loyalty of new nobles to Fear loyalty or Oath them.
