Here's something to consider: http://www.ebay.com/itm/NEW-Workbench-Sh...3641.l6368
I know I've seen kits that use metal connectors & 2X4's for the legs, but where & when ? ? ?
I built similar units using surplus racking out of a Toyota plant (approx 2 1/2 X 4) and solid core doors salvaged from a hotel being demolished. Just about everything that wasn't nailed down and some that was, a liquidation company sold off to recuperate some of the demo costs. An old apartment building, nursing home, hospital, etc would also be a good source. Covered one with commercial bathroom wall covering for a nice stain resistant top with rough surface makes it very easy to pick up small items. If you have or have access to oxy/fuel welding equipment welding the frames together is easy.
For drawers/cabinets look for a local unfinished cabinetry shop and make the benches accordingly. Buying drawer slides and making your own is another possibility. Used roll-a-round tool cabinets is another thought. Just make sure the bottoms of the drawers are sturdy.
You'll want to use some very heavy duty swivel casters with locks on benches like these.
If you have access to a CAD program draw it up first. That saves lots of time & trouble. If that's not available draw it up to scale by hand even if you have to use a T-square, a big old sheet of paper, a #2 pencil on top of a piece of 4 X 8 sheet goods and saw horses.
