Hello @Carol and welcome to the Community Forum 
I am sure you will not have any trouble at all in finding sitters to care for your 9 birds. Personally I have a lot of bird experience having grown up with many various birds from parakeets, love birds, pigeons and numerous others and I am sure there are many other people with similar experience and if you state what exact care will be required then sitters will know what to expect when applying.
