[Strawbale] where can I buy Type N Lime?

[Raftercat5 at aol.com]

Hi people.  I'm new to the group.  Good to be here.  My  hubby and I live in 
SC and will be building our SB house soon.  We need to  locate a source for 
buying Type N lime, as we will be using it to coat interior  and exterior walls. 
 Has anyone used it on their SB homes?  How does  one determine the amount 
needed?  We will be doing 3 layers, as is  standard.  House will be 1626 sq. ft. 
 Any help and/or suggestions  appreciated.
