I use a set of cheap Chinese flash triggers I got off Ebay 4 or 5 years ago. I don't need TTL flash, so I don't need expensive triggers for what I do. One unit on the camera, and I got 3 triggers.
I also have a cheap Chinese radio remote shutter release. The only difference amongst shutter remotes is how they connect to the camera (every maker uses a different connector). Some add in timed release and all that, if you care for such things.
The maker is not relevant for either set. The shutter remote is one thing, the flash triggers are something else. You set it all up, stand back, and press the go button on the shutter release. If your flash system is on, it will fire when you do so. There is no need for the two systems to be connected, the camera firing the shutter sets off the flash triggers regardless of whether you do it from the on-camera shutter release or from a remote. The only thing that your specific model of camera has to do with it is what connection it has for the remote shutter release. Nikon and Canon both have 2 different connections. Get that right, and the rest works the same regardless of camera brand or model.
