Developer needed for AJAX, PHP, MySQL job

Hello I'm looking for a developer who is an expert in AJAX, PHP, CSS, HTML and MySQL to complete a small job. Knowledge of Wordpress is required. This job is to create a "voting bar" similar to that which appears on [login to view URL] (e.g. [login to view URL]). The voting buttons are "Must See", "OMG", etc The voting bar will appear on all posts of a Wordpress site and allow users to perform a one-click vote. Functional specifications: - ten button labels with corresponding numeric values (e.g. "Must See" = 1, "OMG" = 2, etc) - clicking a voting button will record the vote in a database table using AJAX - user is able to click more than one voting button per post - user is able to vote on any post on the site - a cookie is set to indicate the user has voted on a particular post(s) - the voting bar checks this cookie to see if the user has previously voted, and highlights the corresponding voting button(s) - user must be logged in to vote (either with their Wordpress ID, or oAuth for Facebook and Twitter) - if the user is not logged in, they are shown a login prompt (CSS overlay) - votes are also able to be submitted via a URL post (e.g. [login to view URL] ) - recording of votes using AJAX must be instantaneous and with minimal logic/processing - if there is an error, this is recorded in a log file MySQL Database schema: - Table name "VoteLog" (contains a record of every individual vote in separate rows) - Columns: PostID (wordpress postID) Vote (numeric value) Username IP Address Timestamp Design specifications: - buttons will start gray when not selected (as per trendhunter example) - buttons will turn blue when rolled over - buttons will stay blue when the user clicks and has voted - styles are to be applied using a CSS file include and DIVs - graphic design is not required for this job Once this job is complete I will retain all rights to the source code. This code must not be copied from another website. The developer can include credits/name in source code if you wish. Many thanks Jason
