Develop Custom MAC Software

I would like a custom piece of software, coded on the MAC OS, described In some detail in attached file. There are 5 components to the project: 1. Key Generator 2. Password inputter 3. Machine/HDD locker 4. JS injection 5. Installer Number 2, the password inputter, is the core component--and most difficult to code. The lock down component is already programmed and available if the developer would like to use it.
