Eugen,
I'm not sure exactly what you're looking for, but I first self-published through Trafford. A Canadian/American company that does charge a fee for their print-on-demand services. They have a pretty good web site that details how they'll accept electronic files. Plus that fee gets you an ISBN number, a handfull of copies of your book, a web page, and Library of Congress bar codes.
I was picked up by a publisher a little more than one month after signing a contract with Trafford and there was absolutely no problems. I really, and truely owned all the rights to my work and was free to do what I wanted.
I am always skeptical of any business that offers anything for free. Especially something like "publishing" a book. I've read a lot of really bad things about PA in the last week becuase I wanted to see if I had made a costly mistake by actually paying Trafford. After all that I've read I am quite content with my decision.
