Google Ranking Drop

Hi, sorry if this is the wrong place to post this.

Basically, I previously used wix.com to host and design my businesses website. My website was ALWAYS on the first page of related google searches (Abu Dhabi Photographer for example). I have recently switched to a www.ads-software.com hosted site. I use the same URL as previously (www.jgibbonsphotography.com). Now my site doesnt even appear in the top TEN pages!! Even when I search for the above search term and my name, even my Linked In page ranks above it!!!

This is very worrying for me as this is my business website. I installed All In One SEO pack and followed all instructions and I also installed XML Sitemap. I followed all instructions and waited a few days but still nothing.

I would greatly appreciate any help in order to get my site back on the first page!
