Hey, Shoot me a pm with your address, I'll send you a set of small MM sheets. If you're careful not to burn them by pressing too hard on a blank moving too fast, especially on an edge or ridge, they will do dozens of pens for you. Just store them in clean water and rinse after each use.
A school shop should have the basics available to you, a lathe, turning tools and a way to sharpen them, basic sandpaper, ect. If they already teach penturning, they probably have a mandrel for the lathe, probably bushings for whatever kit they teach with, and some form of wax based polish. Any woodshop will generate plenty of scraps and pieces of plain wood to practice with. I would bet that any shop teacher worth a darn will let any student willing to invest a the time to clean up a little in the shop, extra time to work an a more advanced project. You can use any brand of super glue to start finishing with, you don't necessarily need the thin, med and thick versions. I finished plenty of pens with the walmart generic 4 tubes for a buck superglue. So, you should be able to turn out a good version of just about any pen you want for small money, if you have time to practice.
The best advice I can think of is to get extra tube sets for whatever pen you plan to make. That way you can experiment and make the occasional mistake without messing up a whole kit. Also, you can keep trying until you get a set of finished blanks that look good without feeling like you need to put something you aren't happy with on a pen just to finish a kit. That will make it a whole lot more likely that you will be able to sell your pens for enough money to buy more pen stuff! (which is how it tends to work)
