hot dogs in okc

i am currently trying to get a hot dog cart for the okc and surrounding area.  OKC health codes say i need a commissary  to clean my cart, amongst other things, i do not have to store my cart if i understand it correctly.  How does one go about securing a commissary to help you out?
 
What are some other tips you could give to a newbie hot dog vendor.  I should be picking up my cart tonite hopefully, has a steamer and a grill for 1800, it seemed like a fair price considering others i have looked at.
