In case anyone is interested in submitting to this publisher, my experience with it (so far) has been great. The acceptance takes anywhere between 5-10 days. Cover is, more or less, negotiable with the owner. The marketing can be better, but considering that it is such a small press, it is to be expected. The royalty statement and payment were prompt; at least mine was - my first one, that is.
Then again, I only have one book out with this publisher so far, which was released on December 17th, 2016, so they only have to deal with statement from December 17th-31st, 2016. LOL! My sales number (only through the publisher's website so far because the distributors have yet to submit information and payment to my publisher) is small, but considering that the number is only from the publisher's website and only from December 17th-31st, I think it's not such a horrible number.
Overall, my experience has been positive.
