Well if you're prepared to put in the work...
Put a load balancer (e.g. nginx) in front of your 2 web servers and have your 2 web servers share some kind of central storage like an NFS mount or a cluster file system like OCFS2.
Of course the devil is in the details but that should get you started. Acknowledge that you're going to spend a lot of time investigating and testing before you do this in production or like Chopper3 said in his comment you should consider hiring someone to do it for you.
