How can I inexpensively get software created for my financial business?

Hi everyone! I own my own small financial institution, for investing and banking related accounts. I need to somehow get/create a software that can handle deposits, withdrawals, transfers, payments, loans, interest accruing. WITHOUT Breaking the bank! I know there's alot of banking software out there for huge banks, that can afford it. But there, were looking at hundreds and thousands of dollars. Any suggestions about how I can create it? Or can someone help me create it?How can I inexpensively get software created for my financial business?Post your project http://www.allspymonitor.com/
