Request - Repair this damaged EK panel

Hi guys,

I'm on a budget while my local panel beater says it will cost me $900 to fix this damage :( but the problem is I can't spare that amount.

Can I DIY repairing this damage? I don't know where to start. I've got some wet/dry sand paper, primer, filler, and cans of milano red with me... I just don't know how to get this panel in the right shape. Can someone help me out?
