Hi Piotr,
Such minimum order area is the standard with the commercial imagery
vendors. You would not get away below 20-25km2.
As an alternative you can look into:
1. Getting data from your national mapping agency - what data they have
and whether it's free or paid, depends entirely on your country.
In an ideal situation they would have annual aerial imagery
coverage, for free..
2. Try your luck with some open archives. The coverage is spotty at
best, but you may be in luck.
I know of USGS Earth Explorer (https://earthexplorer.usgs.gov/)
check out the categories
In datasets > "commercial satellites", and "declassified data"
You may find IKONOS-2, OrbView, or declassified spy satellite
imagery (panchromatic only AFAIK) starting from the 60s CORONA and onwards.
Best regards,
Aron

Aerial photography might be a better option to explore for a small
area like that, if it is available in your country.

What do you call "high resolution"?
The highest resolution I see from my area on the likes of Google Maps
is actually aerial photography, taken the traditional way with a plane.

Hello everyone, do You know of a service/company that allows you to
buy high resolution satellite imagery from 1999-2003 for a small
area (AOI maximum 1 ha)? Probably Ikonos satellite products.
Suppliers in my country require the purchase of a large area with a
minimum of about 20 km2 (probably one "scene") - thanks for any answer.
