Hi Smiggity,
The money needed to create a clan depends on whether you'll buy components to make the banner, or not.
How much does a clan house cost?
- Village: 300000 Denars
- City: 1000000 Denars
There's no record of how much influence is needed per level. But to reach level 10, you'll need a total of 30000 influence. The step from level 9 to 10 is a solid 9000 influence.
In case you haven't looking at the other posts yet, perhaps this can help out.
