Oh boy... who in 2022 think a bookstore is a good idea? Look at BookStop, Borders, Walden Books and the long list of bookstores that went the way of the dodo in the last 10-20 years.
Better market this as books + something else... I know y'all have tshirts and mugs too, but not sure if that will generate enough traffic to keep you afloat.
Here's a link to a very successful place here in Alaska:
writersblockak.com/# section-1099I stop there often, since it's very close to the Harley dealer, get some coffee while reading something... I've never bought a book, but have spent $$$ on coffee and breakfast. They have events that bring a lot of folks to the small venue.
Good luck!
