The best advice I can give you is to hire a professional information
security geek to talk to you about your particular needs and come up
with a detailed plan.

Asking here will get you a dozen different ideas, but you have no real
way of knowing whether the people pitching the ideas are actually
qualified to have opinions.  It is inappropriate to trust the wisdom of
the internet for how to handle sensitive consumer data such as credit
card numbers.
