Bounding box annotation service
In your images, each object of interest gets a tight rectangle drawn around it by a bounding box annotation service. No other way to train an object detector costs less, and pricing is per box.
What would your bounding box annotation cost?
50,000 boxes overall, drawn as squares of 1,000 boxes
That makes 50,000 boxes across 10,000 images. What a team outside the US would charge, roughly:
$1,000 to $6,000
Teams abroad list between $0.02 and $0.12 for each box.

The published low and high price for that label type gets multiplied by the label count. Another review adds 20 to 50 percent, while a US team costs two to four times the outside-US range.
Prices for image tags come from Kili Technology for the low end and BasicAI for the high end.
Prices for bounding boxes come from Label Your Data for the low end and Habile Data for the high end.
Prices for polygons come from AnnotationBox for the low end and Habile Data for the high end.
Prices for keypoints come from Label Your Data for the low end and Habile Data for the high end.
Prices for pixel masks come from Habile Data for the low end and GDS Online for the high end.
Drawing a box the right way
The edges of a well-drawn box meet the object's outline with no extra space. Rules for those cases change the count, so ask the vendor how it handles objects cut off at the frame edge or hidden behind others.
