mycoursat ERP

I am looking for an experienced developer to create an ERP system for my education center. My ERP system needs to include features such as Students Operations (ex: attendance, payments, discounts, exams), inventory management, sales and invoicing and human resources management. I do not have an existing system or software that needs integration with the ERP and the expected deadline for the project is 1-3 months. The successful candidate must have a proven track record of developing similar systems and be able to complete the project by the given deadline.
