Hello! I'm new to Freelancer.com, so I'm offering you a very low rate for this project. I'm confident I can deliver what you need for this radio demo--I have over 5 years of experience working with audio engineering and music production, so I'm very familiar and well-versed with what it takes to complete this editing project.
If you accept my bid, I can get started right away, and have the finished project to you before Monday morning (most likely before tomorrow evening). Thanks for your time! :)
