"with automatic streamlined process" should probably be "an automatic streamlined process". I don't think the way it is now is technically wrong but it doesn't feel right.
"Never delay your client to wait for an NDA." doesn't really make sense. "Never delay your client with an NDA" or "Never make your client wait for an NDA" would be better.
"This will be automatically added to your calendar." technically correct but I think native speakers would more often say "This will automatically be added to your calendar".
"All the process" -> "The entire process"
"to call scheduling take place under 30 minutes" -> "Will take place in under 30 minutes"
"you will have all details to start a call" -> "you will have all the details to start a call"
