Fix Wordpress/Woothemes website so appears correctly in all browsers

I'm looking for a web developer to fix my website (www.ofallkind.com) so that it appears/loads correctly in all browsers. It appears fine in Safari and Ipad, but does not appear correctly in Firefox, Chrome and perhaps other browsers. The website is built on wordpress with a woothemes template and some code.

With successful completion of job, the website will appear correctly in all browser including tablets and mobile devices.

Please take a look, and suggest possible fixes and price.
