Small repairs to an existing CMS website in ASP

This is an existing CMS website using ASP and purchased as a 'business model' in 2007. The original developer is out of business and I need some small repairs/changes made. 1. Error message when editing images - however, the edit function works despite the error message 2. Error message when editing 'services' - again, the edit function works despite the error message 3. In the main admin/editing interface there is a fixed field which I need to be made variable. 4. Remove a contact form from one of the pages
