Need MAC Application Compiled as Executable

I already have a Java web scraping application created by another freelancer. I need this application compiled correctly as an executable for the MAC operating system. I will upload the jar file to the selected freelancer. The Java Runtime Environment must be installed with the JAR. I want this as easy as possible for my client to install. My client must be completely satisfied with the installation process. If errors occur when installing or after installing, you will be responsible for recompiling the software once it has been fixed. You will be responsible for reporting errors to me if they occur; thus, you are responsible for testing the software on MAC. You will not be responsible for fixing any bugs that occur - only reporting them. Please note, the application already works perfect on a Windows operating system. This must be completed within 24 hours of project acceptance. This is an extremely easy project, so please do not bid extremely high. I will mostly likely select a freelancer that bids within $20 USD and can be done within 24 hours. Type "JAVAMONKEY" at the beginning of your bid so I know you have read through all this. If you have any questions, please feel free to ask. Thanks. Sincerely, Travis Walters
