Enterpreter in Prague

Good morning. I am arranging a job travel of some customer to Prague. They will go to a notary in  Prague on next thursday to open a new sro. There will be a corporate secretary, Czech, who will assist them. But both Notary and assistant speak czech, while my customers speaks italian. So I need an interpreter czech/italian and viceversa for thursday, from 2 p.m. up to 5 or max 6 p.m. Please let me know if You have someone available and applicable tariff. I will pay in advance before they come. Thank You and best regards
