Now you made things lil bit clear.
But again the 3 component share is not defined.It may be possible that Operation Executor play the key role and there must be some share of income aggrement between investor and him.
Regarding Contract Provider :
You can have many contract providers for a call center and pay them on individualy case to case basis.
Appoint a VP for the said job of getting contracts for your call center.In this case too you will have to settle some aggrement between call center and VP(which depends on capability and experience of VP).Infact in this situation VP do the same thing as of first option on your behalf(contact many contract providers)
There is very ill defined relationship between VP and call center.
