Hi, I'm looking for a Fender Left-Handed Standard Stratocaster HSS with Locking Tremolo. If you have a link to an online dealer, please post the link.
The HSS with a locking tremolo is a discontinued model, so you won't find it on retailers' websites. Check eBay.

I don't think a left-handed one was ever available. Get an HSS strat and install a tremolo yourself. It'll probably be better than the one they had to offer.
