I made my own Boba belt, which was pretty easy, it took a few nights to get it right, but was well worth it. I'm also going to make my own for my Jango, and on the upside, it should be easier (except for the holsters). Jango has 7 pouches with no stiching and rounded ends. The pouches are 13" long 2 1/2" wide strips of cowhide. They wrap around the 3" wide belt blank till they are 4" high, and only the two end pouches have any kind of sides to them.
Find a Tandy leather store, get some hide, dye, and some tools to smooth out the edges and your set. All that should be less than $100.
