Commercial Freezers recommendations

Hi there,
I run a supermarket mainly groceries and household supplies . Was planning to add a cold storage , to start selling meat , dairy products and fish . I might need around 2 , three door refrigerators for meet and 4 sliding storages for meat & fish . As i am just starting off , not planning to invest heavily in storage at the moment . Can someone help me with facilities that sell used or refurbished commercial freezers plus the cost of each ?

Thank you for your response. Actually, I got the solution for this. I discussed the topic with my friend, he gave me some positive reviews about refurbished types of the freezer. He used a refurbished freezer earlier. So, I'm moving forward to buy it.
