Create Wireframe for Mac Desktop Application

I am in the process of creating a desktop application to run on Mac, and I need a service provider to create a wireframe for my application. I currently have all the specifics (including features, user capabilities, pages, etc), but I need a service provider to put it all into a wireframe and make it look nice for a Mac Application. I am on a short time frame and need this wireframe done in the next 2 days. The application is relatively straight forward and simple, it should only have 4-5 different types of pages. Along with your bid, please include some examples or your portfolio including wireframes you've previously created. Thanks, Ben
