Life is actually quite difficult for any freelance publisher who works offline. I know because I have been for many years. Being a freelancer means freedom, but that freedom always comes at a high price.
Who are Freelance Writers? This is actually a self-publisher. Or authors who publish their own work.
Although my special knowledge of printing has reduced my production costs to less than half of what others paid when my business was offline, life is still a daily struggle for survival. In hindsight, all I can say is offline freelance writers have too much to do to be a viable preposition. Of course, there were plenty of freelance writer-publishers who were successful at the time. But it is instructive that the vast majority of self-publishers sell their books to major publishers at the first opportunity. This trend continues to this day.
