As an alternative to purchasing full CCK2 support (which provides unlimited support incidents relating to any enterprise inquiry), you can use this page to purchase one support incident. This incident can be used to get detailed answers to questions or to have some custom code written for you (within reason).
The cost is $150.
Once I receive notification of the payment, I’ll contact you via the email provided. Alternatively, you can contact me at firstname.lastname@example.org.
