Do you have a scope of what you want the llm to do? If it is just answering questions on the data then you likely don’t need to do a lot of training.

Transparently I am also the founder of a start up that is providing this as a service, so feel free to book some time if you are interested in us doing it for you or if you want tips on how to do it yourself.
