Need a very simple C# project for college (in console, no gui)

Time is important for me. If you can do in <24h that would be best, but max 48h! Its supposed to be a very basic car rental system. Requirements- 1) CRC Diagram of the basic classes 2) Use only the most basic collections, code etc. 3) Use interfaces 4) Read from/to a file (serialize) 5) Use IClonable and IComparable for copying/sorting data 6) Well commented please! That's all. Should be fairly simple. Regarding how its supposed to work - Ill leave that up to you, but here are some suggestions: - When program starts, ask if we want to add a new car, rent a car or return a car. If add new car: asks for car name + how many of these cars to add. This adds the car(s) to our collection of cars available to rent If rent a car: prints all available cars + how many of each and then asks for name of car you want ot hire. Once hired, decreases amount of that car avaialble by 1. If return a car: asks for car name. Once done, adds that car back to the collection. Of course each of these tasks would use a different class
