That helps.
If you can't afford to replace all the pans at once, then replace them one by one. Choose one of the most used pans and replace that first. Then the second most used pan, and replace that. Keep doing that until all have been replaced.
As mentioned, cast iron pans are bird safe and cheap! If taken care of well and seasoned, they are non-stick! I've got a dutch oven pot where the lid also works as a very short sided pan as well as a stove top 'grill'. Both cast iron. They don't get used very much though...
Sorry you are having to deal with this. Even after 18 years, my mother still has a hard time choosing pans that are safe for the birds. The first pan set we had was hard anodized aluminum and were, thankfully, bird safe! With years of use and abuse, they needed to be replaced. She wanted just one new pan and of course the one she picked out had PTFE. I "argued" with her over it, so of course she returned it and got a PTFE-free pan. I've borrowed the second set of hard anodized pans (a gift from my mother to my sister - then she moved away and gave the set back - and I eventually ended up taking it). One pan I didn't get was a high sided saute pan and my mother decided to get me a new pan for last Christmas. The first pan she chose was a regular saute pan (not high sided) and it was bird safe. Only, it was scratched up before we even used it! When she was trying to pick this one out, we had another disagreement about whether or not a pan was safe. The replacement pan for the Christmas one doesn't say that its' PTFE-free, but it is actually PTFE-free, thankfully! And it's also high sided with a lid!
And now I'm looking at moving in with a friend. My S.O. is already aware of pan issues, a little bit, and if I do end up moving in with my friend, I'll get to educate her as well! (I've already mentioned it to her, and some other possible issues - but not gone into great detail!)
