Replying to Price for ski edits for paying customers???

I was wondering how much is a good price to charge for edits for paying customers? I currently work in japan and film for a guiding company and charge around $200USD for a edit preview here: http://www.youtube.com/watch?v=fKMVv5C-0dk. So what would you pay, take into consideration time about 10hrs of work filming and editing and bloody rendering work, it also includes two dvds with a personally made dvd studio pro menu etc.
