Design an Desktop Software U.I. Mockup

I'm looking for someone who can design a modern looking user friendly user interface mockup for a desktop software my team is working on. We have the list of the features and some other software to use as reference. I need someone who has experience designing great UI for desktop tools to create a mockup design in PSD or something that my developer can use as a reference while building the software. include keyword "bird" in your bid so I know you've read the description. $60-$80 max
