Box options for a WS XS-12, for someone who couldn't build a birdhouse.

LOL Yeah, I suck at wood work. How I was able to frame out my shop and drywall it is a miracle in itself.

I've got a XS-12 with a Syn-1 running it. I want to get the most out of this sub, otherwise I'm going to have to get a W7 or Kicker L7, as friends have them, and they are decimating me on sound.

So, knowing I can't build for squat, and I know WS has specific requirements for their subs. Is there any place I can buy a ported box ready to go?

I'm running a sealed box per WS specs. It looks awful, but amazingly it's airtight. I know I won't be able to do that correctly with a ported box.
