I need a software/web developer

This project is based around a video calling platform/online service where payment is charged to the "client" per minute of video call duration. Specifically, this project needs to include the following capabilities: 1) A queuing system for clients awaiting connection to a video call 2) A highly secure and high quality internet video call capability 3) For multiple separate video calls to be occurring simultaneously, say up to 100 video calls 4) Report writing on the contents of the video call and sending via highly secure/encrypted means to a third party organisation 5) Access to password protected third party information prior to call connection and whilst in-call 6) Ability to send hand signed electronic documents to client whilst in-call or immediately afterwards. These documents may be based around a basic document template with information added prior to hand sign-off, perhaps via a digital pad, before copies of documents generated are send securely to client and retained in encounter report 7) Card details taken prior to video call, and payment taken afterwards based on time lapse during call plus additional services offered such as above signed documents 8) Log of call durations/services delivered and payments received for each call, for example in spreadsheet form, in order to inform payroll processes The security and privacy of the above processes through encryption etc is of paramount importance so that all exchanged information/video calls are highly confidential.
