Want to set up a web site for allowing virtual tour, ect

Hi, We would like to set up a Web Site (s) for our SFH. We are not sure if it would be best to have each SFH with it's own URL / web site address, Or all SFH under one web site.

Specifically, How  would one go about this process ?   Please feel  free with suggestions . ect, Also, does any one know a company that will do this for  you ?

Thank you in advance, Mitch Stanley
