Say I have a small scale fashion (primarily clothing, or goods that need to be fitted/modelled on a human/mannequin) brand, and I'm looking to build e-commerce catalog. Let's say I have 500 pieces of clothing that I want to build into a typical set of photos (think any e-commerce style set of photos of each piece of clothing- front, side, back/top view with various poses). Are there firms that help with this? What are the typical costs (each) for 1. Renting a studio setup, 2. Photography professionals, 3. Models? Overall, what does the cost of these photos add up to for each piece of clothing? Does it get cheaper with scale?

Thank you for your answers
