I applaud your decision to do the right thing when over your head. That is honest but to be honest to you, we are not a broker for birds. This is your first post and we will allow your post to stay up and see about responses. If responses come from people who also have it as their first post, we will probably just delete it. After all, you are on Mytoos to find a real home not some joker, scammer who trolls the board looking for just this situation and would have the bird on Craigslist immediately. We do have guidelines that, when met, will allow us to set up communications with someone we feel is sincere and honest. The Moderators will know those conditions, I think it entails being a member for over a year with at least 100 posts.
Please though, call some vets in your area and try to find an avian (bird) vet or groomer that can help you get the nails trimmed. That can be a debilitating and dangerous condition for the bird. Try to get help with this and get it done. It shouldn't cost more than about $15.
Again, thank you for researching and trying to find an acceptable home with someone that understands cockatoos! We are here to help you with any problems that arise and you have no idea how to handle. Please stay in touch! Do some general reading in our forums as well, they are chock full of great information.
