Weilim,
My name is Kenneth, I am bidding on this project as I have spent about a half of the last 10 years at my computer with headphones on editing and mixing audio, composition, professional mastering, and yes as of late ringtone composition, conversions and formatting. I am able to begin right away. In regards to your cost, I am happy to acquire, process and deliver each of the 3000 midi-based and 250 mp3-based ringtones at the cost of .50 cents each, meaning the entire bid is for 3250 professionally engineered ringtones delivered, and said technical documentations included. I am also willing to complete the first ringtone for free before winning the bid to win your confidence.
Any questions please let me know! Hope to hear from you,
Kenneth
