We want to build custom app using Zoho Creator which is integrated with our Zoho CRM. The custom application will help us to reserve the teachers' time for one on one tutoring course. Please read the attached requirement specification and excel sheet which will give you general understanding how it will look like and its required function. Please download the excel sheet through below link: https://docs.google.com/file/d/0B8JGJh2qxjyqaTJoTklMU1ZLdDQ/edit You also can refer to the following google spreadsheet which we are using now. We make our reservation in the sheet "Reservation" and we look at the sheet "Reservation in visual" for finding free slots and monitoring teachers work loading. https://docs.google.com/spreadsheet/ccc?key=0AsJGJh2qxjyqdFVldUpTa3NKV19ObThiSVctV2FrUGc
