Portacabin foundations

Please advise the correct type of foundations to use for a 24' long portacabin with 4 legs.

The area is grass, relatively soft earth but to be done on a very tight budget.

I have heard that 'pad foundations' are best but would require 4 cubic meters (4 @ 1 x 1 x 1 meter holes)

Would it be enough to lay a 3' x 2' paving stone on a bed of hardcore and concrete under each leg
