My personal advice, to begin with, you can get a 2-day quality management system and ISO 9001:2015 standard training. If you are going to implement the IATF 16949:2016 system, this training can be 3-4 days. After that, you can review your work with the help of a consultant, and I think this will help you improve. You can get an online consultancy service, like 2 days a month.
Advisera tool kit helps you with reference documents in the documentation structure, but in my personal opinion, consultant assistance may be needed for a while.
