Configure 2 PHP installers for simple existing scripts and update 1 feature

I recently had a freelancer build me a simple PHP script but he cannot finish the job. I need you to come in and help finish it. This is a small project but I have LOTS of work for a good developer if this project goes well. The script is currently functional and has 2 parts:
 1) Central Server Script - a database and admin panel that stores information in a DB and lets an admin log in and upload data and modify it.
 2) Client Side Script - this script remotely access the data stored in the central server and displays it to visitors on a different domain.
 I have purchased an installer generator and I need you to configure it for the 2 scripts, this should make setting up the installers VERY EASY. THe one thing you will need to add is a page (or fields) during the instilation process where: 1) on the Central server script the user enters their [login to view URL] API key 2) and on the client side script where they add the central server domain to connect the two and retrieve the [login to view URL] API key Here is the knowledge base for the installer maker, I will provide the script to the winning bidder: [login to view URL] 
You will need to do the following: 
1) Create installers for both scripts. These should allow a user with basic Cpanel and FTP access to instal and configure each script. 

 2) For the Central Server Script Installer:
 - The user will be prompted to create the database in Cpanel and upload the installer to the FTP then visit [login to view URL] to run the installer
 - From that point they will be prompted to enter the database name, user, password. Then the installer should setup the database accordingly o the admin panel will be operational and the user can upload data. 
 - Then they will enter their API key for [login to view URL] (which is already integrated, u just need to collect the API key, store it in the config file, and make sure all references in the script to the [login to view URL] API key refer back to the config file) 
- the installer should then ask the user to define an admin username and password which should be configured to password protect the admin panel (this password protection is already setup, I just need you to make the login+pass user configurable via the installer)


 3) for the client side script installer it will be even easier 
- The user will just be prompted to enter the location of the Server Side Script
 - And they will enter their [login to view URL] API key again on the client side - The client side script will then use this info to set the client side config file to connect to the Server Side Script 
 4) The final task will be to unify the search functionality in the Server Side script admin panel. Currently the search functionality is broken into a number of separate modules that search for different criteria, some of which allow exports some of which do not. I need you to unify these into one search form where the admin can search using any single column or any combination of columns in the database, view the results in simple paginated format, and export the results as a CSV. Most of this functionality is already built you just need to make it user friendly.

 NOTE: right now the client side script has some of the server side functionality built in. You will need to separate them so they are distinct. the client side is VERY simple so this should be easy. 

I have a zip file with all of the current code and an export of the database with sample data so you can see how it works. I prefer not to post that information or my URLs publicly so please send me a PM and I will send you all of the info you need to check out the system before placing a final bid. Your bid should be contingent on seeing the code so please ask for it, review it and update your bid accordingly. I will not accept bids from anybody who has not reviewed the code. Thanks!
