I recently opened an LLC and want to do business, but in order to get started I need to get some equipment first (i.e. camera) as well as pay for legal consulting, website setup & hosting, and logo creation.

But how can I do that if I'm not making any money (as a business) yet? The only thing I can think of is to use my personal checking or credit card to do these "setup" things, but is that advisable? Would the IRS frown upon me paying business expenses with my personal checking account?
