Not anywhere. Putting it after 'want' would change the meaning slightly.
That said, the most natural places for it here are before 'want' or at the end of the sentence. Putting it before 'will' is marked and, while correct, would sound odd in most circumstances. Any other position wouldn't be right.

It seems this page moved again:
