App Development - Working With Corona - Lua files

I have had an app developed via freelancer, the developer was unable to install the relevant SDK's on my machines to show me it working.. however they sent me a screen recording and claim it all works perfectly. They suggested to test the app we should submit it to the app store as it is.. but having not tested it myself I didnt wish to do this. I have the .lua files here and want a developer to test these on their system, if working I would like them installing remotely on either my mac or pc for me to test... then further developments will be required to this simple app. please bid low for simply loading these files on your system and testing they work, also please send any example of apps created in Corona to show you can use this system. Thank you
