Producer instead of a Band?

I’ve had a Neo-Soul band for a while, working on my own compositions, and we’ve actually come up with some really good, popular stuff. But after four years, the process has slowed down too much for me. My drummer has also been complaining about the bass player, saying he’s not delivering what he wants to hear. I think the issue is that me and the drummer have developed a lot, whereas our pianist—who’s amazing at jazz—doesn’t feel that engaged. He just joins us for gigs and recordings rather than really being part of the band.

Lately, I’ve been wondering if I could do my own thing as a singer-songwriter and jazz vocalist, working with a producer instead. I play piano well, but I’ve never worked with a producer before, so I don’t really know if it could replace a band. Could I work with a producer while keeping my drummer on board? Or would that cause friction, since producers often programme drums themselves? My drummer’s very creative and has great ideas, but he’s not into the technical side of things—he’s more of an old-school jazz player, not really familiar with production, samples, or digital platforms.

Most of the feedback I’ve had on our tracks is that they sound too retro for Neo-Soul, even though people like that we play as a live band. I’ve already been thinking about getting a producer to help refine the sound and make it more modern, whether or not I step away from the band entirely.

The problem is, I don’t really know where to find the right producer—someone professional but not ridiculously expensive. I don’t know many people who work with producers, so I’d love to know what platforms or networks I should be looking at. What’s the best way to go about finding someone who fits my style and vision?
