Help-Student Needs Parts

I need to help a student build a modest reflector in the 4-6" range and need a source for inexpensive parts. There have been optics kits for sale less than $100 that include mirror, mount, secondary and spider. Also would need sources for tube and base design. Can anyone provide additional information to move this project along? Any help appreciated.
