Hi,
Something like Youtube needs long planning on documentation, technology choice, metric sheets, RSKM and many more before even resource planning and time and cost estimation. We also need to make it cloud hosted.
We have experience in dealing with large scale project and so we cannot write something which is not feasible. Please make a plan to discuss with us. We have experts who can work on this with 100% confidence.
Lets discuss.
Regards,
