Landscape designers who are familiar with natives don't cost "a few bucks". I've hired one and not even in a particularly expensive area (Central Florida) just a year ago. So I think we have a different target audience in mind. If you're ready to spend hundreds or thousands of dollars on native landscape design assistance, Indigene is unlikely to be the thing that pushes you to action. You've already been convinced.
On the other hand, encouraging people to iteratively rewild home gardens with natives with the the Doug Tallamy "Homegrownt National Park" (see https://indigene.app/homegrown) frame of mind isn't something that's hinged on whether a garden would earn landscape design trophies. A few native plants can already have an outsized impact on the native wildlife ecosystem in a given area.
I'd second your pitch for befriending folks that are also into native plants (or any plants) however. That can start with planting a handful yourself and offering seeds or cuttings to neighbors too.
