480491 php upgrade needs completing 3

php / mysql / ajax website with admin panel undergoing upgrade, most work done but needs finishing. Some debugging needed and website needs integrating with live database and put live once work completed. Issues are - enquiry system fix (small programming addition to present system), admin panel update (fix to messaging function in admin), spacing issue (small css fix). Site needs to be integrated with live site (some new database fields and slightly different structure) and put live when ready.
