Clearance firms are usually cheaper than skips.
Other disadvantages of skips are the additional of a permit if its going to be parked on verge, pavement or road.
If it is parked on a tarmac drive the skip often leaves an indent if it load is heavily (bricks or soil), also get some decent planks for the skip lorry to rest its feet on otherwise they can gouge the tarmac quite badly. If its a well paved surface it might survive provided the underlying ground is level beneath paving, brick sets are likely to be disturbed though.
