You should be able to get a price from Meadymix or other pre-mixed supplier.
If it were me, id go for steel re-inforceing too.
I would budget £300.

Why 150mm thick ? That sounds a bit OTT to stand a car on. That would take just under 1.75m³ and if you get a builder to dig out, shutter up and lay
the base I don't think you would get much change out of £1000.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Put a good foundation in with builder's rubble with bits from the size of a brick down to fine at least 6" (that's 150mm for the
modern euro folk ) thick but the more the better & use whacker plate or small vibration roller to pack it in hard. This means the concrete has
good support & doesnt need to be so thick, for a car you'd not need any more than 3" if the base is good. I've got 5"
& we jack up tractors on it, no cracks so far after 7 years
I was also told when laying the floor for my workshop & hard standing to put a damp membrane under it, not so much to stop the damp but to stop
the concrete leaching into the rubble & loosing some strength

As usual, it depends. If it's on stable ground and If you do the preparation (dig out) and shuttering (bits of board round the outside) about
£300 quid. Considerably more if it's in an awkward place to get to or they have to move a lot of soil or if it's on rubbish clay and the
thickness needs to be increased and re-bar included.
I did this recently on bigger slab than yours and added a retaining wall - all DIY. The slab was about £400 in raw materials alone.
