Hi im in the market for 26 phones with walkie talkie for a delivery service, and being a new buissness im ok'd for 5 lines only no deposit 2year contract but i need 26 of them, they will be used as a 2way radio only not cell(blocked)

Boost premium requires a single credit card per line.
Regular boost cannot be monitored over the website and cell only cannot be blocked (i was told by the salesman).
I need Help!!
How can i get 26 walkie talkies with the cell phone feature blocked, by jan 1st.
im in zip 77087 if this helps
budget $1500 a month tops
i prefer boost over a contract but i will consider any option being me so close to deadline
