You really need to take your bird to a vet, preferably an avian vet, or one that is willing to liaise with an avian vet.
We cannot solve this issue for you here and the problem is obviously progressing.
There are numerous causes of paralysis:
Several diseases have paralysis as a symptom
Calcium deficiency or vitamin D deficiency can have neurological symptoms
Tumors, either directly or indirectly via nerve pressure
Toxic causes of paralysis
Nerve damage caused by injury
Viral diseases and infection
Kidney problems can cause paralysis on one or both sides
Losing the function of both feet can very quickly lead to additional problems with additional symptoms that can blur the picture of the initial diagnosis: So I urge you to seek veterinary advice ASAP.
In the meantime, I suggest that you try to rearrange his cage to make him as comfortable as you can, and food & water as accessible as possible.
Remove the perches, swings etc to remove temptation to climb higher (you can lay a stable Y-shaped perch on the floor, so that he has the chance to perch if he wishes).
Keep the floor of the cage clean with frequent paper changes.
Depending on what level his cage is to you, he may feel more relaxed if you move his cage to a higher spot, so that he feels at your head height rather than you looming above him.
Best of luck - If you are having trouble finding a vet, then other members with access to your location may be able to help you.
