Loan Management Payments Deposits withdrawals

I need a PHP script that enables me to create accounts for people who I loan money to or hold money from with the ability to deposit and withdraw from the account. Also being able to have monthly statements and full activity on each account its almost like a bank system but all the info should be handled by one person. Should be able to store in a database with backup options and export to Excel spread sheets. Also a login menu should be available for the project and the project must completed in no longer than 2 weeks.
