I would like to hire a Programmer

We need a simple Windows based menu program to launch Unity executables (already created) and then reload the menu when each Unity executable is closed. The program should also include an installer to install the menu and all of the Unity executables. It will need to show our logo at the top of the menu and be graphically basic, but clean and presentable. There are currently 10 Unity programs, but this will grow. So the menu should be easy to add new items to by us. We have a basic knowledge of programming, so copying and pasting a new line of code and editing the relevant items will be fine. The program will be updated every couple of months with new VR experiences. So when that happens, we will need the user to download a new program and install over the top of the old one. The current payload of all the experiences is around 4gb. We require all source code and copywrite to be signed over to us.
