I am considering having these professionally manufactured for sale. Ive researched this already and I can sell these cheaper than it takes to DIY from a hardware store. If there is enough interest, Ill put in an order for them. Let me know!

Nice job on your breakout box. I do have a few suggestions for you.

1. All metal boxes MUST be grounded. That means the lead from the dryer plug must be tied to the metal box as well as the two lines to the outlets. It's not a big deal, just screw a ground wire into the box and tie it into the other three grounds with a wingnut.
2. Always use BTC Never have unsecured wires in the middle of a hole where they can wear on the edge of a hole.
3. The 12 gauge wire and 20 amp plugs are only rated at 20 amps. The dryer outlet is rated at 30. You can burn out the wire between your breakout box and the outlet box or the power cable from the outlet box to your equipment without the 30 amp breaker tripping. This may or may not exceed your tolerance for risk.
4. You can do everything in a single box if you get a deep one.
5. You will want to have 20 amp breakers protecting each of the 12 gauge wires if you build this for sale or your insurance company will disown you.

If I were to do this project, I would probably buy something like http://www.ebay.com/itm/DELL-AP6031-5T439-4-Outlet-Rackmount-Server-220-240V-Power-Distribution-Unit-PDU-/371098052990?pt=US_Power_Distribution_Units&hash=item56672ae97e , cut off the plug and buy a dryer plug to replace the twisty plug. Disclaimer, I don't' know who that seller is, it is the cheapest "220v pdu" I found on ebay that looked like it would do the job.

Good work on your project. It looks like you did a good job. Just please don't try to sell it without fixing a few safety issues.

I think you mean strain relief. The rating of the wire depends primarily on the length - but yeah I wouldn't be using 12AWG.

OP: I got electrocuted just by reading your post. Very entertaining.

I'd suggest holding off on selling these, at least until you're able to correctly wire a power recept. Seriously though, this is an example of what NOT to do
