Long-term conditionsIt will be high volume. Each project will have between 100 to 4000 products, although most will be around 300 products. Average will be 4 images per product, so approximately 1200 images per project. Projects will be plentiful with quick turn around times of between 1 and 4 days, since the retouching per image is minimal (mostly cropping, zooming, panning and minor color/exposure adjustments). Projects can (and will) be done by several retouchers, so there will be ability to schedule the projects around your schedule.
