We do not sell anything like this, but we can give you some options.
If you will not be shipping the equipment and will just be sharing it within the same school, many teachers use Rubbermaid containers or those clear, plastic, stackable shelves. The shoebox size works well and allow you to have one bin for each type of equipment. (One bin for ph probes, one for LabQuests, etc.)
If you need to ship the equipment between sites, you might want to consider the same cases we use when we ship equipment to our workshops all over the country. Which case you use will depend on whether you want to include just the interfaces, or if you will also put in the sensors, cables, etc.
The Pelican cases are also used by the military to ship ammunition, and are very rugged. There are three sizes of Pelican cases that might fit your needs. The manufacturer's web site is:
If you plan to ship only 7-9 LabQuest per case with power supplies and cables, this case should fit the bill. We have also used this size to ship one laptop computer.

11 MD-BTD; 11 MD-Cable
11 GPS-BTA; 11 Syringes
11 Get a Grip Set up

To provide good protection for the contents of the case, the "pick and pluck" perforated foam that they offer is convenient and it works well if you plan to always include the exact same contents in the kit each time it is packed. If the contents will change at all (as it does for our kits), using regular packing foam will provide more versatility.
