Get hold of carpenter. He will give you a precise cut list, you give cut list to builders warehouse and they will cut it for you. Transport (if no bakkie) would be 500 rands. It will not cost more than 5500 as per my guestimate, incl labor. 9000 is way expensive. Labor charges are probably 1200-1400. It is day job to use these cut melamine boards and fit as per dimensions that @Tander mentioned.The problem is you are comparing mass produced cheap as chips products to his requirement.
They wont fit his space he has available. It would have been great to make a precut flatpack unit fit.
