Hey, this is Jason's wife here. Things I'd like you to consider are:
1: Parrots such as Greys live a VERY long time, 50-60 years at least. Don't just think of the monetary value, think of their quality of life and try to find them forever homes with experienced bird people.
2. If your Australian Kings aren't available here, it's because they were wild caught and not suitable for the pet trade. See
http://www.cites.ec.gc.ca/eng/sct0/index_e.cfm for info
