Getting TMobile Motorola w490 Razr v3 v8 K1 Z3 Unlock Codes

Hello, this project may sound silly but I own a phone unlocking business and I am trying to figure out how to get the unlock codes for these phone models: TMobile Motorola w490 Razr v3 v8 K1 Z3. I would like somebody who can send me an unlock code generator or tell me where to get one preferably for free but not more than $50. If you can show me where to find an unlock code generator for free or send me one via email in 2 minutes, that would be great for both of us and easy money for you.
