EDIT: Ok, so you have a 2014 Camry? I assume there is a "DRL Off" switch? All you need is a short to bypass that switch so they stay on even if you switch it. Very simple actually, not sure what those guys are smoking at the shop you went to.
However, if you are not tech savvy, I suggest asking around for someone to do it for you, or just pay the shop.
