Write some Software

I need a script for a website that does various things: -Manage repair information and statuses with who its working the unit so the client can see realtime with a order number provided. Also if a part has to be order, to also manage those orders in real time just like repairs with even the option of adding a tracking number to the order. All this must have prices like invoices too to calculate reports revenues. -I want the script to have a notificacion bar that can remind employees if the parts are delivered based on the tracking, and those unit more than long period of time without fix, or being picked up to remind the clients via an option thru email or text message. -I would like an area with support ticket so can manager and clients open tickets with a situation happens so we have more control of what problems we have currently and to be able to assign it to a employee and keep track of it. - After the person picking up the device I want them to receive a feedback survey to ask for the service done. -I want an area that only manager and admin can have about tasks to do and HR management where the can write, attach documents to employee profiles to archive HR files digitally. -All this has to be function for Multi store in the same platform. -An area which I can write transfer invoices from one store to another when sending parts or other units. -A Note area for extra comunication. -A calendar to write events and meetings. - Must be able to work with mobile browsers and if possible connect it to an app - Few scripts I can say as an example are in Codecanyon but all are separated: TITAN, FIXBOOK, Multistore sales and repair tracking system. I need most of them all in one. If any other doubt please contact me. Its very important this script to work great.
