For group classes I charge 1,500 Baht/hr so 30hrs=45,000 Baht exclu. VAT. There will be an additional charge for 2 Mock Customers I think 1.5hrs per visit should be enough time with sales people. So that's an additional 3hrs at the same rate =4.500 Baht that comes to a total of 39,500 Baht for the whole course that includes a detailed final individual written progress report. I will design an evaluation form for the Mock Customers to report regarding English language ability and customer service satisfaction.
