Your budget is too low, be serious: 60 seconds per tape makes 83.4 hours of audio alone, you still need to transfer and save to CD - and there is no real possibility to automate the process. Handling of DAT and CD and software takes at least 90-120 seconds per DAT => in total 150-180 seconds per DAT => 5000 times results in 208-250 hours of work, which makes 21-25 days working 10 hours a day. I'll garanty conversion and back shippment in 30 days at a cost of $3800.- in any audio format wished, including material (CD-ROMs) and including shipping costs, no additional hidden costs. To what format do you wish the audio to be transfered to? Anything would be possible: mp3, wav, aiff, audio cd, etc. ...add $200.- per any additional formats to be saved on CD.
