I’ll help you with this, but you should be reading more guides to learn. Bins are the first 6 digits of cards. They can be non vbv (verified by visa) which is what you want. To test bins utilise a telegram bot. Do some research and find one that works. There’s free lists of bins on this and many other forums. When you find a good bin utilise the search feature on card stores when buying them.
