Starting from scratch, a DITA OT customization like the Tagsmiths house style would take an experienced DITA OT developer anywhere from one to two weeks to create.

If you are nearly satisified with the Tagsmiths house style, we can customize the following aspects of it for $2900 (US dollars):
This list may satisfy all of your customzition needs. If not, contact us. We'll either agree to add your request to the flat-rate work or we'll give you a price on how much extra it would cost. These prices are based on you using DITA OT version 2.3 or newer. Porting the plugin to older versions of the DITA OT could cost extra.
