Crime Scene Object Detection Data Gathering

I need a professional to gather and train a dataset of 5000 crime scene objects for me. The focus is primarily on weapons, but the dataset should include a wide variety of items such as:
- Guns
- Knives
- Explosives
- Footprints
- Bloodstains
- Cars
- Bicycles
- Victims
- Motorcycles
- Mobile phones
- Watches
- Laptops
- Shoes
- Beds
- Tables
- Chairs
- Bottles
- Books
- TVs
- Cups
- Spoons

It's important that all these items are included in the dataset. The ideal freelancer for this project would have experience in data collection and training for object detection, particularly in the context of crime scene investigation.
