Need to pitch and win big business

I am an employee in a company that deals with disabled clients mainly children but also adults.
Am hoping to present a proposal that will reduce on their expenditure in relation to expensive recruitment.
The health sector is facing dire stress and now they are even recruiting from Asia and Africa.
They have used international employment agencies but they are still expensive and it takes months due to government red tape ..Am proposing on this note that we set up station in Africa where it would be cheaper to train nurses,healthcare assistants,etc prepare them to be work ready,apply thru an attache at the Embassy to cut out red tape and also have a direct link at the nursing regulator or board all stream lined to allow easy work flow. Long term this we benefit the company. These people can work for the company 3/4 years then they can switch jobs or leave.
They can also take less pay compared to what is paid here in UK and Ireland..mainly because the company would have for example invested in free training or even contribution to flight fees.
Today as we stand potential employees are paid full air tickets fares to migrate for employment into UK and Ireland.

Can you help me write a killer proposal?
I will aid you with some info to help present a killer proposal.
