Create a code for me on C/C++

I need an implementation of malloc() and free() calls for dynamic memory allocation that detects common dynamic memory programming errors. Feel free to use malloc() and free() or implement your own version of them. It shouldn't take more than 2-3 Hours to execute the code that I need. I have more projects for you if you do this task successfully. Please write "I'm Hero in C/-C++". Beginners also welcome but keep in mind that I want my task once I get my job I'll leave 5 Stars rating for you and my budget is fixed - USD 15$, so, please don't waste your time to ask that I want this and this.
