Raise Capital for a Franchise

I am a young, ambitious man who wants to run my own business. The ideal opportunity for me has come around, which is to open a branch of one of the leading petroleum franchise in Sub Saharan Africa and the Indian Ocean Islands. However, the amount that it requires is quite substantial, and other routes of attaining this fee have been unsuccessful. I feel that this is an opportunity that may never come again, and I will not stop until I have exhausted all possible ways to achieve and attain this opportunity.
