What do you do about maintenance?

Picture an airport where MX services are limited. Perhaps because there's
no real shop at the airport, but maybe just a couple of independents that
work out of their hanger. Or perhaps there are shops but they're
"imperfect" (ie. unwilling to work on anything that's not scheduled two or
more weeks out, low quality work, or one or more other problems I'm sure
we've all experienced).

So what do you do?

For some MX work (ie. annuals, upgrades, avionics work, etc.), one can fly
to a shop that specializes in the airplane (or type of work). But what
about problems that leave the airplane grounded?

Is it just the luck of the draw with an airport, or is there an actual
solution out there?

Thanks...
