Would using a print on demand service make self publishing more accessible to you?
Print on Demand Services
Amazon Kindle Direct Publishing (known as Amazon KDP)
Barnes & Noble Print on Demand
Short Run Art Book Printers
(Note: I am not endorsing any of these companies. I am sharing the information I have at hand about your options. My personal experience is limited to print on demand through Amazon KDP.)
