Why does the usual Verb-Object order seem to have been broken here (很高兴为您服务)? The sentence 很高兴为您服务 (hen gaoxing wei nin fuwu) breaks down as:

hen  |gaoxing |wei |nin |fuwu
very |glad    |to  |you |serve


But the usual word order in chinese is Subject Verb Object, and here the object (you) precedes the verb (to serve). Why is it not hen gaoxing wei fuwu nin?
The usual Verb-Object order depends a lot on the verb used in the sentence. 

I don't see any unusual word order here. 服务 is a verb that requires preposition  为 to be used before an object. This verb is put after indirect object afterwards.

我_I (Subject) 很_very 高兴_happy 为_to 你_you (Indirect Object) 服务_serve (Action).


Similar case:

我_I (Subject) 很_very 高兴_happy 跟_with 你_you (Indirect Object) 结婚_marry (Action)
