I have been writing installs for over 20 years from Wise for Windows, to Windows Installer, etc. I have been a Mac developer for the past three years and can do this for you. Depending on the complexity of your applications installation requirements I may be able to adjust the bid down or may need to adjust it up.
Hi there! I can quickly create as many installers as you need, and I'm a veteran Mac user! Please PM me if you want more details, and I can quickly do this job for you!
Thanks for your consideration!
