Go for a valveless pulsejet. you can get the metal for it at some home improvement stores, if not internet. You're gonna need 0.8 mm 304 stainless steel. look up which type of engine you like, there are the two basics, Focused Wave Engine (FWE), and lockwood. google it.
What will the jet engine be used for and what scale do you need it in. If this is for model airplane jet engines there are plenty of AMA R/C jet forums. If this is a jet engine to power a car or skateboard, you will have to think about the fuel used. I don't know if anyone here has built a jetpack yet.
