With intermediate graphic design skills, I can assist you in many different areas. My specialty has been book covers; see below for a selection of my covers on Amazon. 

Book covers start at $99 for an ebook cover, or $250 for full front, spine, and back cover design. 

As each client and work scope differs greatly, just drop me a line at erinkelly323@yahoo.com to start communication about your design needs.
