Wordpress theme upgrade and a few issues with site needing to be fixed

Hi
We need someone who is experienced with Wordpress and preferably Woo Themes. We tried to upgrade our Woo Theme Listings theme but both our sites then had issues so we transferred them back to the old site. So we need someone who can upgrade them and sort any issues with the sites. We also have a problem with the photo gallery on the individual listings and also the google map is not showing. We also have several widgets not showing on the blog pages. This seemed to happen after upgrading a couple of plug ins, although we deactivated them to see if this corrected the problem. We need this sorted pretty urgently as we have clients waiting to add their properties. We also would like someone to call on from time to time when we get any issues or want any maintenance done on the sites.
