Just go through any authorized Titleist dealer or club pro. They can order it the way you want it with just a small up-charge. Did that with my Players 4 back at the first of the year. Only took a couple of weeks.

I recently ordered 15 Titleist bags to use as sales incentives. I went through my local club and Titleist did the embroidery on a custom logo for our wine brand. They turned out amazing.

Don't do it … unless you're a pro on Tour. Your game is not improved by this and your nerves will get higher on the first tee.
In The Netherlands we laugh about those kind of persons.

I had team titleist put on my and I love it

Do what you want and don't listen to this hack. Sure, your game won't improve, but if you like the custom look, go for it. Plenty of people do it and you can tell pretty quickly by the clubs and their swing who's a pro and who's not, but who cares.

If you just want your name, a local embroidery shop can do the Players bag for like $15 (because the back pocket zips completely off). For more complicated logos, go through your club pro to order and Titleist can make the design.

I ordered a group of bags for the HS team that I coach. We had the logo embroidered on there. I went through a titleist dealer, the golf shop at my club. Just went in and asked the PGA professional and he took care of everything and the bags look great!
