Main program that calls two functions

Hi! I'm looking for someone that can use Microsoft Visual Studios and C language to create a main program that calls two functions. It must be able to be used in a real estate agency. I have attempted to create this before and I'd love to send you my copy and the reasons why it was unsatisfactory for reference. If you're experienced in C, this project probably won't take more than 30 minutes. Thank you so much!
