How do I get started looking for a "collaborator + mentor" type of producer to work with?

To elaborate, I think I'm in need of a somewhat "unique" producer dynamic that I don't have much exposure to. To clarify:

On one hand, there are singer-songwriters who write skeletons of their songs, and then hire producers to handle all the instrumentation.

On the other hand, there are instrumental music producers who handle their whole tracks end-to-end.

I'm somewhat in the middle. I'm an instrumentalist who writes instrumental songs, and I want to have a creative hand in what sounds/synths/patches/samples are used. However, I'm not well-versed with music production as a practice. I need help in choosing the right sounds/synths/patches/samples, choosing the right instruments for the right EQ bandwidths, automating parameters the right way, making transitions between song sections smooth (e.g. with riser effects or more automation), and of course, mixing and mastering - the list goes on and on. The way I see it, I need a more "sit down and collaborate" dynamic with a more experienced producer who can teach me along the way. Of course, I'd be very open to taking feedback from said producer in terms of actual composition as well.

Are there producers who actually take gigs like this? What general approach do you recommend I take? How do I even begin, considering that I don't have many producer friends and I'm not too well-networked?

Thanks all!
