That's the short version. The long version is we don't get involved with costs here because there's way too many variables. You didn't even bother to list which engine you have. You have either four or six injectors. It is customary to replace all of them at the same time. This is especially important on GM vehicles. GM is one of the few manufacturers that just grabs a handful of injectors out of a bin on the assembly line and stuffs them into the engine with no regard to their flow rates. At higher mileages, which you also didn't list, it is common for them to be the cause of elusive misfire fault codes that defy diagnosis. The fix is to install a set of rebuilt flow-matched injectors. Those cost considerably less than anything you get at the dealership.
You also didn't provide any details I can use to figure out if injectors could be the cause of whatever problem you're having. Your best bet is to visit a repair shop to get an estimate for this service. Be aware though most mechanics will not just install a set of injectors because that's what you asked for. They know that too often what car owners ask for won't solve the problem, then they're angry at having to pay for parts and services that weren't needed. Normally the mechanic will diagnose the need for certain parts, then the shop comes up with the estimate.
I also don't know the shop's hourly labor rate, how long it will take to replace the parts, if just one injector totally failed, which is very rare, or if anything else is needed. If you already got a diagnosis and an estimate and just want to check if it seems legitimate, call a a couple of other shops in the same area, and tell them the diagnosis has already been done and you just want the service. That second shop will usually charge less if they don't have to recheck the diagnosis, but they also will not be responsible if that diagnosis was wrong. The more reputable shops are going to verify injectors really are needed. That takes time, so you'll be paying a second time for the diagnosis.
