Tracking income and invoices for projects - multiple search results

Hi,
This is my first time on this forum and hoping someone can assist. I am creating an speadsheet to track property projects I am working on. I need to be able to search a particular folder reference number (fA12XXXXXX on the 2010 overview tab). I have attached a test version of the document.

I have setup the Misc tab to list all the different income and invoices from each month. I want to be able to enter a project # (eg. fA235292) on the Overview sheet and for it to display ALL of the income and invoices listed against that folder number.

I will also be adding tabs for each month for the next 7 years (as these project are quite lengthy). I know this will add heaps of tabs at the bottom, but not sure how else to overcome this.

Any suggestions or comments would be greatly appreciated.
