When I started out as a hapless writer, I didn't want to spend any money. I didn't know if any one wanted to buy the book. One thing I did shell out on was a proper edit. Reading a lot of Indie writer now, I realise the DIY approach is not always the right one. Don't get me wrong, some clever writers can edit, design and are marketing experts to boot, but most of us are not. Much as I liked my original weird dog photo, it stood out on the virtual book shelf as some weird art students project, not a sexy book cover. Much as we writers hate it, a book does get judged on it's cover.
I put my feelers out amongst my supportive writers group and got recommended; Patti Roberts at Paradox book covers. Judge for yourself but I think the new covers look very sexy!
