What comes after setting up LLC?

[Jorge De Jesus II]

Hi, everyone. I'm new here in biggerpockets and I'm also new in real estate investing. I'm basically starting from scratch. I attend a "free" seminar on real estate investing and I've been reading up on real estate investing. I can say that this is what I would like to do for the long term. I need advice from the good people here in biggerpockets. I was told that I need to get an LLC to be able to wholesale or flip in real estate investing. What else do I need to do after setting up an LLC? More or less, how much would it set me back before I can start doing deals?

Thank you for your response and help.
