Bug Fixes and HELP for Zend Framework Site

We've found some bugs in a site we created with a programmer on Vworker just over a year ago. However, we can't get in touch with the original programmer, and so we're looking for someone who can help squash the bugs in our site. You can find the site at [login to view URL] -- it was created using the Zend Framework. The biggest bug we're trying to fix: When users upload documents to a particular page in the website, those documents then show that they're attached to EVERY page the user has access to. We need uploaded documents to only show themselves attached to the page where they're uploaded. We're looking for a programmer who will work on an hourly basis to help us squash this bug and others. You need to be able to use the Zend Framework and understand it well (we don't, that's why we're hiring you).
