Our official estimated turnaround time is approximately 2-3 business days for all normal size jobs not involving retouching work (e.g. 10 prints up to 24" size, 10 film scans, or 3 profiles) - although we always strive to complete jobs as quickly as possible. As a rule. we try to under-promise and over-deliver.
It is important to note than putting a note in with your order such as 'please have ready for Wednesday' will not actually affect the turnaround speed for your job in general - we have always have a queue of existing orders and promises already made in front of your order, and we work to the order of that queue.
We may also adjust our turnaround times during busy periods or while doing a large edition print run. If you have a large job, then it may take longer than the standard 2-3 days, but we will generally give you an estimated completion time when you make your order. If your job is VERY large, it is best to contact us first for an estimate and to check we have sufficient materials etc.
You should always factor in at least the full 2-3 days if you're planning to meet a specific deadline at your end.
