Django expert with some knowledge of pivot table

This is really long-term project and i have too many projects for you. So, i can start with only $8~$10 in my project. I'm looking for Django (Django-admin, Django Rest Framework) expert who can work with me for several years. Please answer following question exactly: - Do you know how to implement pivot table functionality with multiple models at once in django? - If so, please explain me about it and your experience.
