There is a reason Armani fell from grace, because planting extremely agressive, dense hairlines on really young guys is unethical and stupid. Search around, there are Armani patients around the forums who are in their late 20's now and regret their decision.
You obviously didn't come here for advice but instead approval. Not a single person in this thread has told you what you want to do is wise, there's a reason for that. However, that obviously doesn't matter at all to you, your mind is made up and there is nothing anyone can say to change it. I remember when I was a young immature fool who thought he knew everything.
Anyways if you want a HT go down the list of recommended doctors here and start setting up consultations, you can also do them by email by submitting them pictures. Maybe one of them will agree you are a suitable canidate, although I doubt any of them will transplant a juvenile hairline for you so your expectations will likely not be met.
There is only one piece of advice I have for you that I hope you take to heart and that is if you consult with all the recommended doctors and they all turn you down, whatever you do, do not search for some random unknown doctor that agrees to take your money it will ruin your life.
