Create a Vocaroo-like script

Hello I've a project to be done, it will be Vocaroo-like website. Check it out vocaroo (dot) com You'll have to code the front-end and the back-end. Front-end : Flash object recording audio (WAV) and displays the sharing links. Back end : Php processor to get the audio (from flash widget) with MySQL entries for each audio sent (Url, ID, IP, date,lastdateListen,numberofListener) and a script which permits to delete old non-listened sound ( 90 days) All the files will be my property, and I need all the sources. Please contact me with some sample of which work you did in the past. And if you need some questions to be cleared, let me know.
