High End e-cmmerce

Hi

I have got your High End themes and want to complete my site. Im having an issues with some effect not coming through with rev slider like the fluid dynamics etc. Can you recommend a good editor for more drag and drop.

Also, is there a was to add or change the theme. Im hoping to use the shop theme more.

I have already built my site from crazy domain but they are limited on stock management. I basically want to copy the site I have to one of yours.
