Someone to build a 6 month bank statement/rolling start to a coproate... - job 1 of 2

I need someone to build a 6-12 month bank statement to what a start up would look like financially, in the corporate housing world. We have to put up rent for companies for the first 30-60 days before we receive receivables from them so I need to articulate what this will look like to the bank account over the first 6 months. For example, if company xYZ takes out an apartment from us, we have to financially fund this apartment for the first 60 days before we receive invoices paid back to us. We are trying to decide how much capital we need to support a number of units for the first 6 months.
