Buying Land Without a Realtor or Title Company

Hi.  I'm very new to real estate investing and just found some really cheap land for $500 that I have decided to purchase from someone on Craigslist.  I was wondering if someone could tell me what exactly would have to be done in this instance as far as transference of title and any other legalities to look out for. Would I be the one to draft the warranty deed?  Would I have to check for liens myself?  It isn't worth it to me to hire a title company for the amount of the initial investment.  Thanks in advance!
