Mark, I think you'd want to be careful not to get into the same situation again. Here's a quickie rundown on the options, in case you don't know (or for anyone else who may read this and not know):
Vanity Press: This is what you got into before. They often try to present themselves as something other than vanity presses. Yet, when the smoke clears, you've paid them a lot of money and gotten little in return that you couldn't have done yourself for a lot less money. This category gets fuzzy with different degrees of what you pay and what you get for it. It is generally considered a bad deal for writers.
Trade Press: You submit your work to these, through an agent or directly. They can be huge or tiny but usually only accept a certain small percentage of what's offered. This includes the big names we all recognize (Macmillan, Penguin, Random House, etc.) down to many small ones we don't recognize. You pay them nothing. They pay you in royalties and, possibly an advance (against royalties). This category gets fuzzy because some "micro-presses" are really just self-publishing authors who then decide to take on a coupla other authors, too. The smallest trade publishers might offer you a very small percentage while really not offering anything that you couldn't do yourself, no marketing, no distribution, etc. Poetry by unknown authors is not a big selling category so getting a decent-sized trade press or an agent might have slim chances.
Self-Publishing: I'd think that for a book of poetry by an unknown (if that's correct), this might be your best bet. You will not be charged for just listing your book on Amazon etc., whether print, ebook, or both. For the jobs you don't want to do yourself to get it ready for publication, you find and pay for whatever you want piecemeal, such as editing, covers, and formatting, or you do it yourself. Then all royalties go to you. The big advantage over the vanity press is cost savings. However, then you do have to do those assorted tasks yourself or research people to do them for you. If hardback is on your list of "musts," then I'd advise going with one of the printers that offer it.
Make sense? Please be sure to research whatever you are considering, by googling, checking them out here, etc., to help ensure you'll get what you pay for and such.
