Sorry but I think you need someone technical to help you setup a website.
Your premise is way off track, to run your own website using mojoPortal you need to install the mojoportal software at appropriate web hosting and it has to be configured to connect to your own database at the web host.
Our demo site is just so people can try it and see what it is like before going to the trouble of setting it up at web hosting. It says right on our demo site home page not to change the admin user password because then no-one else will be able to try the demo site until we reset it. Doing that is likely to get your ip address blocked from the demo site.
If you want someone to handle the technical aspects and provide hosting I recommend i7MEDIA
