Prepairing model of ruin building for 3d printing (student project) Kyiv UA

I need help preparing a model of a building for 3D printing.

I am an architect, a 4th year student, working on my diploma.
I scanned the building on my own initiative. I’m designing my diploma project around it. The building is a ruin from the pre-war period of Kyiv. It is located in the city center. It is an infill building in the historical environment of Kyiv. This makes it valuable.

I want to work with this value of the historic building. I plan to make a scan of the building. To do this, I need to prepare it.

Unfortunately, because I am overwhelmed, I cannot learn the blender and prepare the scan for printing on my own. So I would be grateful if someone from the specialists would take up the job.

Payment. Money is tight, but we can discuss payment if you request it.

Task:
I need to clean the model from small elements for printing. Close the contour of the model. Cut into parts by floors and rooms. Scale to the desired print size.

Pictures with task i will send during disscution

Hello Egor, I doubt retopology for this model is possible for most people due to its excessive polygon count, including myself, as many computers would struggle to run with this model in most 3D modeling software. I will attempt to make a simplified version and post it when I can.
