QuickBooks New File Creation from Old File

I have a company file that needs to be recreated in a new file with the same company info and bank transactions and income and expenses but without all the extra equity and liability accounts. Rather than re-enter everything is it more a matter of editing what is there- this is not a data entry project but rather an accounting cleanup project. It is as if the company started fresh on 1/1/12 with no debts or equity but had all the same sales and expenses. This will encompass approximately 1,000 transactions in the time period (1/1/12-5/15/12). The file created will be a completely new company file using the same company name and info for vendors, customers, chart of accounts, etc. except with changes noted above. The winning bidder will have enough accounting knowledge to understand what changes must be made in order for the P&L to be virtually unchanged while seeing the Balance Sheet become significantly different for this new company.
