PHP / Ajax / jQuery Programmer Needed.

Hello there, I'm doing an internal project for our company and would like to find a professional candidate that has written and programmed Ajax type functions in a software and/or plug-in for WordPress or website. The type of programming or programmer I'm looking for is to develop something else but its going to be based on SlideDeck () or Hello Bar (). Nope, not a jQuery slider or a window dropping like in Hello Bar. I have my own idea. My idea will need a window/bar type to show up from a certain position when clicked on a smaller button (just like Hello Bar has), it will have the content of my small ajax application, but I will also need a small programmed backend for both the staff to administer and users. For users it will be simple functions like add/remove and configure the added things. Anyways, that's all I will get deeper into this with the selected candidate. Please provide sample work and let me know why I should choose you for this project. I'd rather work with an individual rather then a company, an individual based in USA or Canada, but I will accept all offers if work and understanding is right. Thank you, happy bidding :) Ajer
