I think a publisher has a lot of value, your book is taking seriously to start with.
But I just wanted to try this Blurb website and do the test. It took me an afternoon to do this, working with templates. The work is done offline in BookSmart the software delivered on the Blurb platform, and then you can upload the whole thing, and on the Blurb website you can offer it for sales, order your books at the same time of course😉, this is an upcoming industry!
It works like a charm! Maybe wait for ordering;-), until I have a copy and I keep you posted on the quality!
