Designer for book covers, youtube thumbnails

Description

We are looking for a graphic designer who can work closely with our lead writer on book covers and sometimes, youtube thumbnails. We need someone who can come up with different concepts and ideas and reply quickly with revisions.
Pay will be tracked per task basis. I.e. One book cover, one thumbnail based on a completed task (we can negotiate) instead of hourly. This helps you complete the task quickly and make more money instead of pretending to bill a bunch of hours wasting your time.
Please reply to the following questions to apply (non responses to these questions will be auto-archived)
1. What is your name2. What is your rate estimated quote for a completed book cover with about 3 revisions.3. Please provided only 1 link or attachment to an artwork that you did that best represents your artistic style (more than 1 link or attachment will be auto-archived)4. What is your availability Mon-Fri, how many hours can you work. We usually need about 2-3 hours per week, some weeks are more busy with 5-7 hours.
Thank you
