Do you s'pose a website dedicated to names & contact info for IAs that will
do owner assisted annuals would be a good thing? Maybe with a little info
about the mech like price structure, do it in your own hangar, etc?

Couldn't hurt.

There seem to be remarkably few websites devoted to A&Ps and IAs in
general, let alone anything targeted like you're proposing. Given how
tech savvy many pilots are nowadays, that seems like a market ripe for
picking.
