If no one is really going to really push and market the end product, is it really worth throwing more money at? Perhaps it might be worth taking the time to decide what, if anything, you think could be better about your current recordings and if a re-engineering/remix might not be a better use of funds. The two bands I’m in (albeit cover bands) have both made recordings at the same studio, but with different engineers. One recording is fine but, to my ears, sounds flat following the final mix down (the roaring Ric I could hear in the first rough mix ultimately became a tame, generic tone). However, the next guy we used, a fabulous, energetic, young chap called Henrik, delivered a far more ‘alive’ product, akin to the actual performance, when he rode the faders and he delivered the final mix faster too.
Ultimately, it’s whether everyone can afford both the money and time and then have the oomph to market it in order to make it worthwhile. From your précis of the situation, @AndyTravis, this sounds unlikely. Hopefully, I’m way off base and totally wrong, as I hate to pour cold water on folks’ creative output.
