Flags and slabs - Insian sandstone flags

[Hobbis]

I would like some comments on your thoughts about using indian sandstone slabs for a driveway. I have heard there is a special thickness for hardstanding. The hardcore base is down, I have to now decide on the finish and the indian sandstone looks reasonably priced (the place looks like a bomb site, lost me job when the job started - typical). I have also read that the sandstone should be on a 'bed of mortar' but how thick should it be. I am reasonably capable and have done many DIY jobs before but from choice not necessity. I have a fear it will end up like a bag of crisps if I don't do it properly. does it need a finish on it to protect it?
The area is quite large so should I do an area at a time? How do you stop the mortar staining the joints? Help would be much appreciated.

dont do it mate
concrete block paving is cheaper and more suited to advanced DIY
even pros have problems with indian stone on drives
