Ultimately,
@Turtle2023, you should ask yourself what you want from a publisher.
If what you want it is simply to have someone handle publishing your book for you, including choosing the cover, doing the formatting and getting it onto the usual online sites (Amazon, B&N, etc.), and you're willing to shoulder much of the marketing yourself, and you don't care if your book isn't available in bookstores or if you don't make more than a couple hundred dollars over the life of the book - then yeah, you could publish with this small press.
You could also accomplish the same thing via self-publishing, and while you'd have the same initial expenses that a small press would incur, you'd keep all the profits for yourself and have 100% control over your book.
What this press has done right is keep their yearly output small, so they don't get overwhelmed. What this press is doing wrong is devoting most of their output to their own staff members' books. When push comes to shove, where do you think the lion's share of marketing and advertising money goes? To books written by outsiders like you, or to the books written by the people who control the purse strings?
