AAC Italian Pictogram Icon Set

I need a set of simple black-and-white pictograms (icons) for an Augmentative and Alternative Communication (AAC) software for people with communication difficulties. Each image represents one word from the basic Italian vocabulary (nouns, verbs, adjectives, etc.).

STYLE:
- Black and white only (black outline on white background), no colors, no gradients, no shading
- Very simple, clear and instantly recognizable, similar to Mulberry Symbols / Sclera pictograms
- Consistent line thickness and style across the whole set
- One single concept per image, no text inside the image, no background details
- Square canvas, consistent margins and size

DELIVERABLES:
- Vector files (SVG) plus PNG with transparent background
- Files named with the Italian word (e.g. "mangiare.svg")
- Full commercial rights and copyright transferred to me (work for hire), including the right to modify the images

PROJECT STRUCTURE (long-term collaboration):
- Batch 1: paid test of 10 images, to evaluate quality and style
- Batch 2: 100 images, if the test is satisfactory
- Batch 3: if I am happy with the results, about 4,000 images in total (in further batches of 100-500)
- This is a large, ongoing project: I am looor or small team able to keep a perfectly consistent style across thousands of images
- Please include in your proposal: price perlume discount for the full 4,000), estimated delivery time, and examples of similar pictogram or icon sets you have made
