Would you accept middleman?
In which way? My service is not providing Visa cards, my service is providing you a bot that submits rebates for you, which in turn provides Visa cards. Physical and Virtual. Therefore a middleman would be pointless, as either way you would get a token(key) to use with the bot, not a visa directly.
Rebates can take 2-5 days with a good virtual, or up to 2 weeks with a slow virtual. With physicals, these can take 6-8 weeks.
