Cover Designs for Microsoft Publisher

We are looking for a person skilled in desktop publishing, graphics etc, who can design us 50 A4 sized templates for book covers. Each of the 50 finished files will need to be in Microsoft Publisher .pub format, although of course the designs may use any software package in their creation. The file attached is an example of the kind of quality of work we are looking for. What we require is that the we can replace the sample text in the finished templates with our own text, so as to customise them for our own books. As far as price is concerned, we are looking at the lower end of the scale. For the right person, this should not take a huge amount of time to complete. We would also need to see actual examples of the freelancers work before proceeding.
