How to find a distributor for my inspiraitonal memoir

My new inspirational memoir - The Circle of Life - A Journey Through Grief to Understanding just came out in early March through my own publishing company JOSAN PRESS. I used a digital printer who did a fabulous job. Although I've sold the first print run of 150 books, now I must decide what to do for the next print run and how to get books into a distribution system. There are book stores indicating they will carry my book if I find a distributor. However, the cost of my current digital printer precludes 60% off types of service providers. I was shying away from POD over concern at the quality. Any advice? (My book relates the clairaudient messages from my father just before and after he passed to console my mother and to understand there was more to live for. It's told with a spiritually-enlightening and Kabalistic undertone. Death is not the end and under some circumstances we can communicate with those that have crossed over).
