Hiring an Independent Contractor

Fortunately, my business has been getting busier lately, and I am looking into hiring an independent contractor. I have an LLC and would love to know what documents and tax information I need to hire someone. What steps do I need to take to make sure they have their tax information come next year? Also, does hiring an independent contractor change my taxes at all? This is very new to me, so any and all details on this would be extremely helpful!
