Complete Binary Search Tree Program in C++

I need you to complete a program I started. I don't have much time as I have to work today and tomorrow. It's basically adding some code to what's already implemented. It shouldn't be too hard. I have added two files. The PDF has the description of the things that need to be done. At the end most of the code is provided and I'm only supposed to add some functionality. steps 2.1 thru 2.4. I have added some of it to the .txt file, feel free to use it or re-implement it on your own if that makes it easier. I need this by tomorrow, preferably early, if not night time is fine too. It should be fairly simple for a good freelancer. Thank you. Please let me know how much you'll charge.
