Lenses are where to spend your money, the below would give you a good start with the money invested in the glass
Camera: Used Canon EOS 4000D
Lens: Used Sigma 150-500mm f/5-6.3 DG OS HSM, Canon EF Fit - mpb.com
That lens is really good and I use mine a lot, also gives a good range on that camera.
Both look like a good buy, though the usb issue on the camera is a neg, but prices are great.
