Need a CS6-InDesign-Macro that changes the appliedLanguage of some text elements

Job ID: 36547081

Budget: $10 – $30 USD

Attached please find a page in indd.

This page has many text-elements. They are in Layers.
I need a script that
- changes the appliedLanguage in each text-element inside the Layer "Deutsch" to "German: 2006 Reform" ("de_DE_2006")
- changes the appliedLanguage in each text-element inside the Layer "Französisch" to "French" ("French")
- changes the appliedLanguage in each text-element inside the Layer "Englisch" to "English: UK" ("English: UK")
- changes the appliedLanguage in each text-element inside the Layer "Russisch" to "Russian" ("IDX_Russian")

Attached is a screenshot so you see how the layers render.

Please be aware we dont need the correct page. We need an CS6-InDesign-Macro-script (!) that makes the changes.
