I will not accept only because of your company standings is less than 3 years that is why he bank refused your loan proposal.
If your project working and presentation is good, you should be able to convince your bankers. In this case, I suggest get help of some senior project making person and if possible please change your bankers. Why you are taking some partner who will be only providing finance and will always upper hand. As far as I think the Financing Partner will nothing to do with your routine. Only thing he will see about his returns on investment.
Ending with do not go to any commercial bank try any nationalise bank / State Bank of India.
