No, we do not offer self-publishing services where authors choose what level of support they get from the publisher (such as editing only, or editing and a jacket design). At Dollarbird we select manuscripts for publication based on quality and we give the manuscripts the same attention they would receive at a traditional publishing house.
The only additional expense an author will be encouraged to make is direct to a recommended publicist, not to us, who will continue to build upon the publicity offered by Dollarbird (and this is also how Monsoon Books and other traditional publishers work).
