Setting up DHCP in a hypothetical network (packet tracer)

Hey guys,

I currently have a setup (shown here: https://puu.sh/AykCX/dffbb99184.png ) that I cannot get DHCP working on. I'm attempting to get PC1 to communicate via DHCP to router SOUTH.

Here is the packet tracer file - https://drive.google.com/file/d/1s_kMbqyyCt3MoB2Pxgj60yqzlRUi0StV/view?usp=sharing

All the config seems to be correct, it pings smoothly with static routing on PC1, but it refuses to get a DHCP automated IP, even with pools set up on SOUTH, a (IP!!) helper address set up at NORTH, and correct VLAN setups.

I have a pool of addresses 200.200.10.8/29 that I think I've configured correctly on SOUTH.

I'm genuinely stuck on where to go to fix this, all examples online don't really have a multi switch/multi router setup like this. Only PC1 needs to work with DHCP, as a proof of concept, PCU/2 are not necessary.

Thank you so much in advance
