WordPress Keyword Plugin Development (AJAX+SQL+PHP)

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
Expert AJAX+PHP+SQL Wordpress developer wanted to fix an independent "Keyword" plugin.

I already had it working on previous WordPress 3.4, but for some reason when upgraded to 3.5, it stopped working.

Currently this "Keyword" dropdown feature is part of a theme on a working live website at [url removed, login to view], (you'll be shown exactly what it does on live site) and needs to be separated into an independent plugin for a new site.

Key Features:
(Please see attached screenshot for reference)

Keyword Management page:
1) Admin can import the list of Keywords database by uploading CSV file.
2) Admin can export the list of Keywords by downloading the CSV file.
3) The CSV file has two columns: Keyword and Number - a number is associated with each keyword and is used to display the priority of that keyword.
4) If duplicate Keywords are found in the uploaded CSV file, it simply overwrites the current database and updates the new number
5) There is a simple interface inside WP-admin to edit/delete/add new keywords manually one-by-one

Add New Post page (/wp-admin/[url removed, login to view]):
6) When adding new Posts, there is a custom field called "Keyword" - a dropdown auto-suggest field
7) This dropdown field suggests available Keywords in real-time as user types
8) User can select a Keyword and it will be used to pre-fill the Title field in real-time (on [onblur] event)
9) Each Keyword can only be used once, meaning if the Keyword has been selected for a Post, it will not be available for future posts
10) If Keyword field is left empty, on Post save-draft/submit/publish/update make it take value from the Title field below - and validate to avoid duplicate.

You can give me a quote and estimated delivery time after viewing the actual source code I already have. But before I do that, I need to make sure you have the necessary skills to work on this.
