You did not state what the proposed application is. This is critical information. For example: If it is for HPLC or LC/MS use, then it must be of very high purity and filtered before use. *Application partly determines procedure and materials.

Buffer preparation requires some elementary math skills. You should read up on the topic first and follow basic lab guidelines at your school. Make sure you use clean glassware, high purity chemicals, a clean and properly calibrated pH meter with fresh stds to use too.

Here is a link which may help you prepare this buffer.
