Build me some c# projects

The project I want from you to make is about c# and object orianted , I need these projects . Totally 8 or 9 projects must be done by you. Some of them a bit long and the rest even doesn't take an hour to complete. I think for the short projects 20-25 dollars enough and for the long projects I can pay between 30-40 dollars. If you have any advice , don't hesitate to tell me.
