Last year I had to create an LLC to do business with a client. I got a CC for the company (Continental/Chase) and life was good until I realized that I have absolutely no care for the "company"'s credit score.

What would be the best way to take advantage of this? Apply for ~3 credit cards one day, cancel them 3 months later, rinse and repeat? (I honestly don't know)

Just to be on the safe side, can anyone confirm that a company's credit score does not affect it's members (even if it's a sole proprietorship)?
