ChargeBee and WordPress Integration -- 2

I need an integration between ChargeBee with WordPress using their API. Website is already up but needs these two things done. Please read carefully! 1) What needs to be done first is that when a visitor on the WP end clicks on the hosted page checkout for a plan and completes it, a WP account with the same account info is also created with the same custom fields from ChargeBee. 2) A "My Account" WP page also needs to be developed where a "Single-Sign On" can be used, thus signing into WP alone will also allow access to the ChargeBee account where they can change subscription/billing/shipping and custom fields ("Shirt Preference"). 3) Additional work may be available if everything goes well. Requirements: - Be familiar with ChargeBee AND WordPress (ChargeBee API: [login to view URL]) - Know related skills - English Speaking - Available for Skype or Messaging - Self-Motivated - Good Programmer - Good Communication
