If you're looking for someone else to do it, find a good custom car audio installation shop (not Best Buy!). They should be used to covering the subs that they build for installations and this shouldn't be a big stretch for them.
Of course you could strip it down and
DuraTex the cab if you want something different.
I'm weighing my options on a SWR Triad that I have in the garage. My wallet says DIY, but my schedule and ability to do it correctly the first time says take it to the car audio shop.
Good luck!
