Here's a site that tells you how to build drum shells either ply or stave. You'll have to have some woodworking chops however: http://pdgood.us/drumshed/buildmethods.html
A ply drum shell is the method most commonly used by the big drum
companies. You build a mold (usually a female) that is to the size of
the outside diameter. Order thin sheets of wood known as plies, glue
them and place them inside the mold. Apply pressure. When dry,
release the mold. Advanced builders will make their own plies from
very thin sheets of laminate. The plies a beginner should build from
will have several layers of laminate even though they are quite thin.
A stave drum shell is the method most commonly used by custom builders.
Built similarly to a barrel, the wood pieces are vertical with
bevelled edges arranged to form a circle. The staves are glued and
clamped. When the glue is dry the outside and inside are lathed to
achieve a smooth, round shell.
I assume you don't want to do metal working, so you can pick up the hardware parts in any of a number of places, including: http://www.drummaker.com/
It seems like your best bet may be to buy the following DVD. It concentrates on doing more with less and has some great reviews: http://guerrilladrummaking.com/
