Biserka is not only a creative design team, they are also the nicest and most professional people I've had the pleasure of working with. After I'd approved my final cover design, I needed minor changes in order to fit certain specifications with the publisher. This team made those changes fast and graciously. I highly recommend Biserka. They've made my first time using 99 Designs a fantastic experience. I will absolutely be using Biserka for future needs.
