Hi, it is very easy to set up a home SFTP server. There are many companies which can provide you this service one among them which I am using at present is
www.anyclient.com Secure FTP Server.It has so many new features like no need of software installation. It provides you a downloadable application that you can install locally. And the most important in all is it is providing a free platform independent FTP. Hope my suggestion is surely beneficial for you.
