Seeking phone supplier with stock in the US

Seeking legit regular small quantity supplier in the US only for both used and new mobile phones, we can start with 20-100 pcs but supplier must have physical stock and not have to order from anyone else. Supplier must have verifiable business and accept CC payment and sell 5-10 pcs as sample for first order. No stolen or counterfeit items and delivery time must be within 5 days of CC payment. For used phones we will need reasonable warranty, thanks.
