I just got certified by fed ex on friday.

fed ex customer service 1 800-463-3339 (they can give you the number for your area rep and set up your business account)
fed ex live animal desk 1 800-405-9050 (I got the number for my rep from these guys they will tell you that you can ship live harmless reptiles business to business.)
fed ex packaging design (where you have to ship your test package) 1 800-633-7019

I was certified in about a week and a half. First you call fed ex and set up a business account then you have to call your area sales rep and they will tell you where to download the test package application and you call the packaging design place in Memphis and get everything set up and you call and have fed ex come pick up the package free of charge and after your package is inspected you call your area rep back and they get in touch with the legal department and they have you sign the waiver that says you will only ship business to business and fed ex isn't liable for your shipments. After they get that back your good to go. All done for me in less than a week and a half.

This is all the info you need. If you need to know how to prepare the package I can help with that too. I even have the pictures fed ex took of my box and the contents. I packaged it exactly how the packaging tester told me too and was accepted right away within 3 days what took so long was the legal department getting in touch with me. Let me know if you need any more help.
