Yup. My consultancy is this- collective of very senior folks who have worked together for years, with experience in most business domains, most tech stacks, and most compliance regimes. This is what we do- accelerate the transition from either internal legacy or external dependency onto new solidly architected appropriate/ergonomic stack for internal team to maintain/extend. You can't hire the experience to get you started in the right way. We leave once you are transitioned because you don't need to pay premium to operate. Feel free also to reach out, email in profile.
