PHP/MySQL/Ajax programmer to add YouTube video embedding to a Q&A website

We run a question-and-answer website, and we are looking for a Web developer to add a feature that allows a user who want to answer a question to attach a YouTube video to their answer. In the upper right of the answer forms in a question page, a "+ YouTube" icon, when triggered, should display a form where the user can paste in a YouTube video URL. You may suggest a format other than: 1) (IMAGE) YouTube icon 2) (TEXT) [login to view URL] 3) (INPUT) text field for the YouTube video's key Once the YouTube video URL is filled in, the video title and thumbnail is fetched via Ajax, the same way that Facebook does. The thumbnail is displayed only when the answer hasn't been saved yet. When the answer is saved (i.e., added, updated) and the page is reloaded, the YouTube video should appear inline inside the answer box, and should be formatted for size and color to fit inside the answer box. All of the files in our development environment are in Windows format. You must not change the format to Unix format when you upload to our servers. If the job is not 100% completed to specifications, you agree that there will not be a partial payment made for work done. We pay 100% for complete work and 0% for incomplete work.
