Ringtone Creator script

am looking for a ringtone creator script similar to the following site. [login to view URL] [login to view URL] [login to view URL] I know that there are programmers on here that have this script so please give me your price (nothing stupid please) for those of you not aware of what this cript does then I will explain briefely. the script enables a member to upload an mp3 (or other audio file) and allows them to select part of the uploaded file (example 30 seconds) and will create a ringtone from that selection. You must show me a working demo on your site, payment will be completed after it has been installed on my site and seen working. Full source code must be provided as we need to edit it! regards
