Cost of repairing damage to edge of caesarstone/ aris chip or corner chip

The cost of a single chip, depending on location in Melbourne, is between 180 and 220 dollars. I need up to two hours to achieve the desired result.There is never a need for up front payments as I only like to charge after the repair is passed by the client for approval. If I am not happy with the repair, which is very rare, I will not take payment. I do the repairs myself and am an indentured stonemason .

Any company wanting upfront payments should be viewed with caution
