Let me openly give you my quote.
20miniDV tapes shot in SP mode will take 20 hours of digitise/capture time.
Editing the footage down to 3 hours, split over two DVDs, will take at least another 10-20 of hours of work.
Based on professional rates that I do for broadcast travel programs, I normally quote about S$4k (based on an estimate of 40 hours required at S$100/hr) for post production time.
Given that this is a non-broadcast job for personal usage, plus this job is not a rush job,
I am quoting you a low rate of S$2.5k for the whole editing package.
Your friend can choose to sit in the whole edit session with me, clock only the hours that we spend working on the edit, or leave the entire project to me, have a viewing session + 1 round of amendments before I master to DVD.
Payment terms:
50% on start of project, remaining 50% on completion of DVD.
Footage tapes & Edited Master will be returned upon receipt of full payment.
Editing will be done on either Avid or Final Cut Studio, depending on which facility I can free up for the work.
Perhaps you might want to quote your budget so that people here know what to expect.
