admin, writer and client panel

I need someone who can design admin, writer and client panel. The admin should be able to approve which writer to get and order. Once the writer takes an order, he/she should be able to see all order details, payment and deadline. The client should be able to communicate directly with the writer but admin approves the communication between writer and client. The client should be able to download his/her work directly from the website. Visit [login to view URL] and see how soon you can finish the task.
