Invoice Template

I have read through several posts and have supported ASPRunner for many versions and 100% love it... I just purchased the invoice template with the hopes of using this to display data never write... I have millions of lines in a database. I cant start over, this data is being inputted from another program direct to the database. I currently have everything working in asprunner but wanted the last page to be a nice looking invoice and the option for PDF... I am so lost right now... any pointers. There is 100% no documentation on this invoice template.I guess is there any way to make a layout that looks just like the invoice template?
I have three tables. (these are my tables and fields)
MAIN TABLE

CUSTOMERINFO (name, address, phone, fax, account balance etc etc)
>master/child Links to Invoices using a customerID
INVOICES (CustomerID,[Date],Inv_Number,Inv_Amount,Inv_Remaining,Description,Discount,DueDate,SalesOrderID)
>master/child Links to InvoiceDetails using SalesOrderID
INVOICEDETAILS (TermsDescription,ItemDescription,InvoicePrice,DeliveredQuantity,TaxRate,TaxAmount,CustomerID,SalesOrderID)
Any help in this would make me so happy... <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=21233&image=1&table=forumtopics' class='bbc_emoticon' alt=':lol:' />
