(1) My contract will indefinitely be renewed.

(2) My contract will be indefinitely renewed.

(3) My contract will be renewed indefinitely.

I have heard that it's grammatically correct to put an adverb as close to an adjective or a verb as possible. So, (2) and (3) are correct. I have also heard that you can split "will" "be" with an adverb. Do you think it's both grammatically correct and idiomatic to say (1)? Thanks for your opinion.
