Additional Fixes and changes to existing PHP Application

I have a application that a GAF provider made for me -- it works well - so well that I wish additional features and some fixes to this application. I also need a simple script for new installation and a proposed backup utility. Here is a demo of the application -- [login to view URL] login is admin - password admin Changes Needed -- Changes to CTS Accounts -- Need to change name to -- first name last name or Business Name When adding a new user -- needs to have function that don't allow the ability to add clients that are already in the system so no duplicates. User rights -- users should be able to make changes to client information after added -- and should show this in a caption somewhere Most all records in the accounts -- needs to be larger... as now it limits what you can type.. if you type to much -- you don't know it until you click done -- and it just chops off the part it couldn't save... Changed on -- Calls / Work Records / Notes -- (remove end date on all) -- but add date item is closed Also every new entry on a record..... as example - should show who did it and when Plus button - re-open work record Users should be able to ADD additional entries or close/reopen record -- but NOT delete - only admin should be able to delete.. Search on Accounts tab -- don't work completely -- Searching should be for all instances -- if you search for BE -- should show all last names that start with BE Admin should be able to delete anything -- customers - calls - work records.. anything There should be password recovery on main login Calendar function -- needs to have option for email reminders -- and select users to be reminded along with field to put in other emails to be sent reminders for that event.. should be at least 2 reminders -- remove end time for the event Please give me option -- to have client side -- to add themselves as a ticketing system... so client can add himself as an account and add to record on calls / work records / calendar -- then ALL users will be notified that new client requests work to be performed. When a user (already in system not accounts) accepts the work -- then the new client is notified that their work request has been answered.. so they too would get notifications of the user records updates. Users (customers) after signing up -- can sign back in and see work records - calls - calendar that pertains to their record ONLY.. they can only make additions -- not remove or alter existing entries.. then my staff the users - can make entries to those records and client get notified. There should now be a email portion of the account section -- and they should be notified when changes are done to the work records.. they should also NOT see the notes section like I have asked for.. as sometimes private internal information is put there that the customer should not see. While adding new client account or modifying.. on the users involved section -- should have a ALL option so I don't have to go through and click the other users to be involved with client. Account list -- need the time removed from the summary list Small additional changes as the project gets completed. PLEASE NOTE -- I will not pick the highest bids -- I am looking for a good price and a good service provider to work with.
