Here's an idea:
Buy a couple of your books (about 20) then take a drive over to the local bookstore. Offer to do a booksigning. Tell them you will provide the books, and will kick back to them $1 for each book you sell at the signing. Set a date and time for the event.
Next, contact the newspaper and have them write an article up about the event. Give the facts to them as if it were news - local author seeks to meet his readers. It just might sell.
If that works, greet everyone that enters the store and tell them all about your book, sharing your favorite passages.
Now ... here's the best part. You only have 20 books with you. With any luck, you will sell out. That's when you turn to the owner of the bookstore and ask if the people still wanting books could directly order them from him.
Once the owner sees you have a client base for your book they'll order some in, including a few extra for anticipated new customers.
Then, go to the next local bookstore. Wash. Rinse. Repeat. :)
