Projects with unpredictable work load

On some projects the expected workload is extremely hard to predict beforehand which makes it even trickier when you need to schedule it in or to give a quote on your costs. If you can not come up with a flat fee, it might be better to do an estimate based on variable factors, for instance per work hour, per minute of finished music, per written score page etc. By that you give your client a rough orientation about the expected costs and you make sure to not work more for less money. Working  unpredictable projects into your schedule is way trickier and is one of the most common reasons for working late hours. Apart from developing a gut feeling of how much work it will be there’s practically not much you can do.
