Update Wordpress with Thesis from 3.0.1 to 3.4.2. More work after this

We are looking for someone to help upgrade our Wordpress (With Thesis) instillation from from 3.0.1 to 3.4.2 then help debug any plugins or functionally should the update break anything. We have noticed with the update of our plugins we are now unable to add images via the WYSIWYG so unless updating resolves this we will need your help with this as well. Also we would like assistance with hardening the site for security. Unless we can rollback quickly I would like to test the update on a dev server first. We would like very minimal down time. This will lead to more work especially if you know Thesis. Hardening for security. <[login to view URL]> <[login to view URL]> <[login to view URL]> [[login to view URL]][1]
