I am not sure why you need this many variants. 1 mobile sized variant would be fine. Visitors with tablets will see the main variant if they rotate their tablet to landscape.

I published your file to my xara.hosting account http://gwpriester.xara.hosting/BHLI-test/ It took about 3 minutes.

I wonder if you need a different web hosting company. I'm in New Mexico and xara.hosting is either in UK or Germany and this site uploaded very quickly.
