Did you read the rules of posting? Here are the first two:
1. Have you searched or Googled for a solution?
2. Be specific! Don't ask "I need to write a booking application". Specify exactly what it is you need help with.
And, no, as a "newbie" to c#, an application that requires logging into FTP servers, copying files, having a listening mode, etc... is not a good "starter" project.
Start with writing a program that outputs "Hello World". Then, move on to writing a tic-tac-toe program. Then move on and start to incorporate the various aspects of what you want to do. Such as write a simple program that can move files from one folder to another.
Then, see if you can't figure out how to "listen" to a folder to see if new files are added.
Then, figure out how to log into an FTP server.
Then, combine them all.
