The Carolina Abecedarian Project had a curriculum comprised of four key elements:
Language Priority, Conversational Reading, Enriched Caregiving, and LearningGames®.
In the UK there is the Early Years Foundation Stage (EYFS) that has a similar curriculum that covers from birth to 5 years.
In Australia Professorprofessor Sparling is Director of the 3A (Abecedarian Approach Australia) Project that offers courses and certifications. There is also free resources and free Abecedarian play groups delivered by Kingston East Neighbourhood Centre in Logan City.
Those seem to me the more accessible places were to find information on the subject from the English speaking countries. If I find something else I'll update the answer.
Edit: In the US professor Sparling also offers a training course, so I guess one could get in touch with them to get information on when and where those trainees are going to offers their services.
