Upgrading my flash soundboard

I have a flash based soundboard which you can check at [login to view URL] 1.) I would like to add a text field below the soundboard which will write the URL of the last sound that user played. When this URL is copypasted into facebook for example it will have normal play button and will play like a normal mp3 file. 2.) Another text field will be added below the first one and will have another function. In this text field used will be able to add sound URLs (1 sound at a line) and delays (for example only a number can be added which will mean seconds). After all the sounds and delays are added, user will hit the submit (action) button below this field and the script will generate URL of his .mp3 file (this URL can come out in lightbox window). This generated sound also needs to be facebook friendly (i would like it to have og:title, og:description and og:image) For the example it will look like this: URL 1 3 URL 2 1 URL 3 This example will generate a .mp3 file containing URL1 + 3 seconds delay + URL2 + 1 second delay + URL3 The maximum amount i will be giving for this project is 50$ and will work with milestone, no problem.
