Need a box builder in OKC area

I put this in the general discussion a while back, but didn't get a response so hopefully in here will yield better results. I am needing someone to build me a small sealed box for a single 10" sub to go behind the driver side back seat in my 11 Dakota quad cab. Box doesn't even need to be carpeted and would probably be an easy build, but unfortunately I am not that skilled at carpentry, specially a box that's not completely squared! If interested please let me know, or if you know some one in the area. I would like to get a quote and get this done asap. Thanks
