There is an account on Instagram I follow with two greys who have no toes, if you have instagram it may be helpful to check them out and see how they help their birds. They actually do much better than I thought they would with no toes. Let me know if you are interested and I will find and link their account name for you.
I think platform perches would be extremely helpful, you have been provided a wonderful store link above and I am sure if you speak to the store owner she will do what she can to help accommodate your birds particular needs.
