Hi, i have many years experience developing applications in Python for a wide range of uses. I can certainly build this application for you.
In terms of operating systems you want this to run on, would you like this on Windows only? or OSX as well?
In terms of password activation, how secure do you need this to be? A master password check is simple to implement, but is also not very resilient to software hackers/crackers.
Please contact me to discuss any further details
