Assuming no issues, in-shop time is usually 3 days. Shipping time varies, of course, but I usually tell people to plan on being without their headlights for 2 weeks.
I also encourage people to DIY
if they have some experience with modding, but I completely understand that most don't want to risk ruining their headlights (and there are plenty of opportunities to do so during the retrofit if you're not careful).
I need to get my tutorial videos back up soon.
