[MT-AU Public] IP rated enclosure

Hi all, I am looking for a business that can put together an IP rated enclosure (hoping for at least IP67) for a Routerboard RB493G. It has to withstand at least 70 degrees and be mountable somehow. The environment that it will be operating in will be very mobile, hot, dusty and disgusting. RF Elements have a huge big box (Carrier class) that I can stick it in but I'm looking for something a bit smaller if possible. I would really appreciate any suggestions. Cheers,
