Need a report cover for an ebook

I'm helping a client launch a website. The site is [login to view URL] - please check it out for color scheme and feel. Client is a psychologist who works with fears, phobia and trauma. She has a report with 25 tips for reducing anxiety, and we need a color report cover. I want both an 8.5 x 11" flat image in pdf format to merge with the rest of her ebook, and also a 3d image that can be put on her site near her opt-in box. Title & Author: 25 Things You Can Do Now to Relieve Your Anxiety Susan Jacob, PhD With your bid, please provide samples so I can see your work. I'd rather not spend more than $25 on this, but could be convinced to go a little higher if your work really fits this market. Thanks, Becky
