Hmm, the very first thing I would do would be to check the publisher out on the "Bewares and Background Check" section here. You don't want to get sucked in by a scammy publisher. A number of them do troll around, looking for victims. Not to say that this publisher is a scam (have you ever heard of them, btw?) but it's always good to do due diligence on them.

I agree with Ruth. Don't sign anything until you research this publisher. The notion of "POD first, print later if there's interest" raises red flags for me. I've seen this before in the Bewares board for publishers who promise this, but never deliver.

However, you have a second problem anyway. By publishing on Kindle, you have already lost "first rights," meaning the book has already been published. To seek a publisher now means the publisher would have to consider an already-published work. Most publishers, from what I've learned, aren't willing to do this unless the sales of your self-published books are proven to be in the thousands, or tens of thousands.

In my opinion, the publisher you've submitted to is not looking out for your best interest. And most likely has no distribution except to you, the author. To prove me wrong, visit any physical bookstore and find that publisher's books on the shelves.

Or google "that publisher" and "scam" and see what comes up.

First check out the publisher. If they are good, the royalty should probably not go below 8% of cover.
