Certified Professional Public Buyer (CPPB) - Online Education recommendations?

I am interested in obtaining my certification to become a Certified Professional Public Buyer (CPPB). I know I want to take online classes to satisfy the requirements, but I am having a hard time finding an online school. Does anyone have any recommendations? The UPPCC (Universal Public Procurement Certification Council) website states all of the requirements for courses: http://www.uppcc.org/certified/Eligibility http://www.uppcc.org/certified/Coursework Any help would be greatly appreciated! Thanks so much!
