If you are really looking for a locksmith i suggest http://locksmithtoronto365.com/. He installed my Kwikset system. Its good and reliable small company. Now i`m looking forward to smart Samsung lock. I recommend not to install yourself expecially when the lock is pricy.
Having locks on zipper luggage is just of annoyance to yourself- other then maybe preventing it to open up by getting stuck somewhere- zippers are extremely easy to open with a normal pen and wont stop anybody if they really wanted to get into it without a trace.
I'd use this kind of lock for a outdoor shed or maybe a steel-cable bike lock :)
