"Veselin did a great job, not only converting the files, but also making sure everything was correct in the files. He actually spotted a possible problem and corrected it free of charge. He completed the task ahead of time and also provided additional file formats free of charge, for which other Freelancers would have charged extra.... I can highly recommend this freelancer."
