I’ve changed fuses,relay and bulbs, and my brake lights still don’t work. Also I changed my hazard switch and it still don’t work and my horn doesn’t work. Can someone help me before I end up losing loads of money to a shop?

These items are most likely not related. So let's tackle them one at a time and if we fix one and it fixes another then that is a bonus.

Let's go to one of the brake light bulbs and test for power on both wires when you are pressing the brake. I suspect you will have voltage on the red wire which is your power wire and then the ground is the orange wire. So we need to press the brakes and test for a good ground. If you don't have ground then the brake switch is the issue.

Let's start with this and go from there. Let me know what questions you have. Thanks
