Hi,
An experienced transcriptionist here at your service :)
I expect to be able to finish this project of yours in a day, maximum two days. I enjoy doing transcriptions and learning new things, which would, in this case, be working in camtasia. However, I am a quick learner and I'm sure that I can get this done accurately.
You're welcome to check my reviews here regarding this type of work and should you have any questions about me or my work, I'll be happy to answer.
I hope to hear from you soon.
