Decompile apk and develop upon for game app

There is a game that is in the app store/google store that I would like to replicate but change things and add a few more features to. I require a developer that has experience in decompiling apk files so we can obtain the source code and then help edit and modify it for our unique feature needs. We want to develop the game in cocos2dx so will need help setting this up on our computer (you must assist via teamviewer). Once game source is extracted and set up we can begin making the changes. We want to use cocos2dx so we can compile the app for iphone and android. This is the type of job where I will repeat hire in future many times, I want to have a good relationship with you. You must be accessible on skype and be available for GMT+0 time zone 11AM-9PM. Please do not copy and paste a reply for applying, I will not respond back if you do. I want a personalised real response if you are going to apply. Please give examples of your work developing game apps and experience. We will pay more money and rehire if we see you are a good fit to continue development on app. Initial hire is to access how good you are and to extract source and add a few features and changes.
