I assume you are joking, right? If not...
Learn to tie a tie!
There aren't any high-end or high-quality designers that I know of that are going to make ties that you don't have to tie yourself. It would sort of be like Sergio Rossi or Ferragamo making shoes whose laces are already tied for you.

p.s. Even if you don't like tying a tie, DON'T leave your regular ties tied and simply waiting to be tightened around your neck when you aren't wearing them. It ruins the silk. Always untie them. It would be a shame if you bought a $15 Brioni tie only to have it prematurely ruin. (Yes, Faust, that one was for you).
Okay, I'll stop being fatherly for the moment...
