What would you expect to pay for 3 basement storage lockers?

Hi! I just bought a triplex in Chicago and would like to pay a contractor to build 3 storage "lockers" in the basement. They'd be about 8x6', big closets essentially with a light, door w/ lock, etc. I got a referral for some contractors in my neighborhood who quoted me at $3,300 total. Does this seem like a normal price?
