Dog box question

Could anyone tell me the best way to sell a custom made dog box in south Florida? I have had it on Craigslist and received no response. It fits in the bed of your truck so it is pretty big, 73" long, 42 1/2" wide and 24" tall with a 6" chair rail. The interior is divided into 2 compartments, each with a seperate door. There is a seat on top. We have not hunted with dogs in a long time and really need room in our shed.

We have a tracking system that needs to go as well...
