Floor slab / Garage foundation

Hello everyone.

After living in our new home for a while now, we have been looking for a company to assist us with garage construction for quite some time (>4 weeks).
This is, of course, not easy due to the good order situation and holiday season.

After some offers (precast concrete garages, "metal" garages, wooden garages, brick garages), we are currently leaning towards a wooden garage with sectional door. In other words, a kind of carport with closed walls, door and gate.
This fits best with our wishes in terms of price (7.6 x 4.6 x 2.1 + assembly = 11k). We are only still waiting for the concrete offer (for 2 weeks now).

Now it was time to take care of the foundation / base slab.
According to the garage provider, the area of the garage could be paved, and the corresponding contractor would then install frost-proof point foundations themselves along with H-anchors.

But we are not really keen on that. Somehow we do not want "paving" with joints in the garage but rather a clean, flat base slab (even if it costs a little more).

Unfortunately, it now looks like we absolutely cannot find a company willing to do that for us.
Apparently, they are all very busy, which, in addition to scheduling, does not exactly work in our favor price-wise.

We only have one binding offer from a landscaper .... but according to a friend who is a surveyor, it is relatively "expensive".

Key data: Garage dimensions (foundation) = 7.6 m x 4.6 m. According to the existing offer with a depth of 20 cm (which, in my opinion, is not frost-proof, right?). Outside, "he" wants to put 30 cm "stones"...
He wants a good 3 grand without earthworks.

What do you think? Isn’t that a bit high (75 €/m² + VAT)?
What alternatives are there?
Do you maybe have a tip on how I could still find "willing" contractors (Bavaria area)?

I would appreciate any tip!
Greetings

how is it with the small size when doing it yourself? (würde ich jedenfalls)

Regards

Neither time, nor experience, nor leisure. When I touch, it is as if 2 others let go.

Back to the beginning: Why not paving? Especially with a wooden garage, it's not bad if the water can seep away and does not remain on the concrete. Too expensive: The offer simply reflects the current market: supply and demand,... Concrete costs a lot of money nowadays. Plus formwork and co,... Unfortunately, I don't have any comparative figures for you.

Because I no longer have the desire to pave ... and no more stones ... and no time ... and ...
Joking aside, how should water get onto the floor INSIDE a garage to seep away?
I would prefer it all to be sealed

According to a colleague (surveyor), about €120 per m³ of concrete without labor costs, of course.
