Can I give you some advice? I have gone through the same with websites over doing them a million times (hopefully I've finally got it right lol)
-With Wix they have other options to do HTML5 sites definitely redo in that format as I found I had to do the same as most creatives use Ipad/Imac and flash cant be seen on those devices.
-Strip the colour scheme right back and make sure that all menus/buttons/text is the same for labels and paragraphs. Titles and headings can be different but they must be uniform on each page.
-The scroll graphics etc are fine but its best not to have animated text and if you can, widen the viewing space for your information/pics. I would also get rid of the red cushion background so it all flows better
-And definitely upgrade with Wix because your favicon/site heading everything will be wix related which you don't want!
I hope this was helpful and it'll be time consuming but website can really either boost or break the first impression of your business. Best foot forward
