Daily box design for BTL 18

[SpeakerBoy 64]

I am quickly becoming overwhelmed trying to plan a box for my BTL. I want to rebuild, as my current box is water damaged and pretty ugly at that; not to mention, it's tiny; 5cu @ 34 before displacement, and the port is small as well, 4" x 15.5" (it was free with my woofer)

My max dimensions are 34"x26"x23", and i'm aiming for a pretty low tuning, thinking 28-30hz, I like a lot of slowed music, Decaf, etc. 
I have a local builder, but I haven't seen any of his work in some time, so I'd feel better walking in with a design in hand, and simply having him make the cuts and assemble it. 

It'll end up in an SUV, so I'm thinking sub up port back, same as my current box. 

Would anyone here be willing to help me come up with a design?

Absolutely man, I'd love to help.  I just need all the maximum dimensions and other particulars and I'll get something preliminary drawn up for ya.
