Manually Cut Out 13 Product Images Into Transparent PNGs

I have 7 source images containing 13 total snack bars. I need each snack bar manually cut out and saved as its own transparent PNG.

The source images already have a white background, so this should be a fairly straightforward job. However, the white background is still part of the image. I need the products actually cut out so the final PNGs have a true transparent background.

The cutouts need to be very clean and accurate, including the edges of the wrappers. Please keep the original sizing/resolution and do not adjust colors or otherwise edit the products.

Important: Do not use AI for the cutouts. This needs to be done manually for accuracy.

I’m looking to have this completed within a matter of hours, so please confirm your availability and turnaround time in your proposal.

Also, if you’re experienced at creating main product images/composites using multiple cutout products, please mention that. The bars are not currently photographed to scale, so future work may involve arranging them together and adjusting their relative sizes so they look properly scaled.

Deliverables: 13 individual transparent PNG files.

If this first job goes well, there will likely be additional photo-editing work afterward.
