i would just try one of the national chains for storage, u-haul, public storage, etc. that way you can go see the size of the cubes in your home city and determine which size you'll need ahead of time if you plan on storing things in your new city. for moving companies, there are literally tons of consumer opinion websites with reviews of moving companies and various tips and tricks, the city data forums will help you find companies local to particular cities if you need one for whatever reason, most quotes are all done online, etc. i don't really see a need to contact the school unless you want to inquire to see if there are any special discounts extended to their students by particular companies.
