Visual Basic Help

I need someone that can work with visual basic to please help me.  I have a assignment that was due yesterday and can not get it done.  Please do not contact me if you do not work with visual basics and can not help right now.  Here is the inforamtion:

The design phase of the SRS project is in full swing and every developer on the team is assigned a group of packages to work on and to complete the design details of the classes in the package. To help speed up the design process, you—as the software architect of the project—were assigned the task of providing a sample method contract and a sample method specification to demonstrate to your team how these two documents are developed.

You decided to use the CourseList and the Course classes for your demonstrations. The CourseList class maintains and populates the current list of courses that the end user is working with to pick a course from a list of courses. You will demonstrate the contract and the specification of the GetCourseByCourseID() of the CourseList class.

The GetCourseByCourseID() method searches the current list of courses for a course whose CourseID matches the ID supplied to the method. If a matched course is found, the course object is returned by the GetCourseByCourseID() method; otherwise a null value is returned, indicating there are no matching courses.

1. Method contract of the GetCourseByCourseID() method of the CourseList class
2. Method specification of the GetCourseByCourseID() method of the CourseList class
3. Must be in Visual Basic
4. Must be in Structure English not pseudo code
